Everyone deals with family issues, but some people had more dysfunctional childhoods than others. Are there ways to tell? According to family psychologist Caitlin Slavens of Mamapsychologistsand therapist Rachel D. Miller, Ph.D., LMFT of Hold The Vision Therapy, yes!

Slavens says, "As a family psychologist, I’ve seen how growing up in a dysfunctional family leaves its mark. Sometimes the signs are glaring, like obvious chaos or neglect." However, she said the signs can also be "more subtle" being that they're "things you don’t even realize were 'off' until you’re older." You may even "start noticing patterns in yourself or your relationships" if you've become retrospective, according to her.

Here are all the subtle signs you grew up in a dysfunctional family

1. You're never sure what kind of mood your parents will be in before you walk in the living room or kitchen.

Emma Bauso

Let's put this on record: parenting is tough — especially on top of trying to maintain a work-life balance. But, this doesn't mean you're meant to be unsure of what to expect every time you come around your parents. If you have to "'read the room'" a lot "before speaking," Slavens indicates this is one of the more subtle signs of dysfunction.

This is where you may have learned how to become passive-aggressive if that's something you struggle with. The reason for this is because "clear and direct communication is avoided and/or seen as bad or aggressive," according to Dr. Miller.

2. You tend to feel like you're constantly compared to and in competition with your siblings.

August de Richelieu

My heart truly wants to believe this isn't intentional behavior from parents, but I can't say I haven't heard people talk about feeling like they'd never measure up to the 'golden child' of their family. You may have felt insecure about your grades, the college you chose to go to, your career goals, or even your physical appearance. Slavens says this "struggle with self-worth or second-guessing yourself constantly" is yet another sign that your family's dynamic wasn't the healthiest.

Also, Dr. Miller says this could've caused you to learn to "shrink yourself in the presence of loved ones." Even worse, you may "feel the need to hide pieces of yourself in order to be loved and accepted."

3. There was constant yelling and screaming during arguments, making you fearful of disagreements or hardships.

If you grew up in a home where arguments always led to screaming and yelling, chances are you're not a fan of loud voices or hard moments. Honestly, Slavens says it's not hard to believe that "conflict make you anxious, even when it’s minor." Unsurprisingly, you may have become a referee during these arguments and currently find yourself being a mediator in your platonic or romantic relationships. Why?

Dr. Miller says, "You constantly feel the need to manage everyone else’s emotions often at the cost of your own needs and wellbeing." You know, to keep the peace.

Here are some more obvious signs you grew up in a dysfunctional family

4. You had to take on a parental role when one of your parents decided to stop being an adult.

I imagine that having an emotionally immature parent is one of the most aggravating and stressful things to deal with. Not only that, but you may have had to help keep the household afloat. You may have had to get a job or two to help pay bills, listening to an adult conversation as your mom or dad laid their problems at your young feet, and more!

If you "family roles were flipped" and you "maybe had to parent your own parents," Slavens says this is a form of emotional dysfunction.

5. You weren't allowed to go anywhere with your friends because your parents wanted to keep an eye on you at all times.

Ketut Subiyanto

Slavens says boundaries that "didn't exist" or "were rigid and controlling" is a sign your home was a little...interesting. Being concerned about your whereabouts is one thing, but it's another when you're unable to do anything without your parents' eagle-eyes on you. Something as simple as going to the mall with your friends may have become a lecture about the dangers of shoplifting or car wrecks. Again, these are valid concerns but they shouldn't be treated like the verbal form of doom scrolling.

6. You consistently witnessed one of your parents abuse alcohol or drugs at home.

Ksenia Chernaya

This is a tough because substance abuse is so prevalent in varies socioeconomic statuses and communities. From the functioning alcoholic to the one who becomes belligerent after they've had too much to drink, it always affects those around them. Slavens says if "there was ongoing neglect, substance abuse, or verbal/physical aggression," your home probably didn't safe.

I recognize some of these signs of a dysfunctional family. But that doesn't mean they're affecting my current relationships, right?

Ron Lach

I hate to break it to you, but it's possible your childhood wounds have shown up before. "Dysfunctional dynamics don’t stay in childhood — they tend to creep into how you connect with others," says Slavens. Similarly, Dr. Miller agrees that "we typically repeat what we learned at home with our families in our other relationships." How?

"This includes the beliefs and rules we follow, often completely subconsciously, about what can and can’t talk about and why, as well as what emotions are allowed to be expressed, who can express them and how, and how we should or must respond to those people and their emotions," explains Dr. Miller.

Another way to look at this is how Slavens has outlined it:

In Platonic Relationships:

  1. Overextending yourself to please others, even at your own expense
  2. Feeling like you have to "earn your friends' affections.
  3. Avoiding vulnerability because it feels unsafe.

In Romantic Relationships:

  1. Struggling to trust your partner or feeling overly suspicious
  2. Repeating patterns like dating people who are emotionally unavailable or controlling.
  3. Feeling overly responsible for your partner's happiness — or relying on them for yours.

OMG! How do I unlearn habits from my dysfunctional family?

Antoni Shkraba

Honestly, everyone has a few bad habits they've carried from their childhood to adulthood. You're not an outlier because some things weren't 100% normal so I don't want you to feel like you're a failure for not having having it all together. "Dysfunction doesn’t have to define your future relationships," Slavens assures. Dr. Miller says you can start to unlearn things "that aren't working for you anymore" by "gathering your family's larger context to gain insight into how and why, for them, the behaviors make sense."

By taking a look at your family's "history and larger social and political contexts" gives you a chance to "see them as whole people with full lives," she says. Once you do that, she believes "you can examine what pieces make sense for you to keep and what parts you'd like to learn to do differently." Her other suggestion? Don't forget you're ability to utilize a "therapist who works systemically, like an LMFT" who "can be a huge support in this process."

Anastasia Shuraeva

Slavens' tips include the following:

  1. Practice self-awareness: Notice when a response feels automatic — like people-pleasing or shutting down during conflict — and ask yourself, Is this helping me, or is this a leftover habit from the past?
  2. Set boundaries: If your childhood lacked healthy boundaries, learning to say “no” without guilt is a game-changer. Boundaries protect your energy and teach others how to treat you.
  3. Learn healthy conflict skills: If conflict made you feel unsafe growing up, it’s natural to avoid it. But healthy conflict is necessary in relationships. Practice expressing your needs calmly and directly.
  4. Therapy, therapy, therapy: A good therapist can help untangle the messy, “weird” things that got normalized and give you tools to rebuild healthier ways of relating to yourself and others.
  5. Surround yourself with healthier models: Whether it’s friends, mentors, or books/podcasts, seek examples of functional relationships and start observing what feels different.

While you're busy unlearning things, Dr. Miller also wants you to remember something. "Recognize that how your family does something is simply that; how your particular family system figured out and were taught to navigate the world. It isn’t inherently right because you’ve normalized it nor is the way another person or family does it inherently wrong," she says.

Slavens' final thoughts? "It’s not about blaming your family but recognizing how your experiences shaped you — and giving yourself permission to do things differently. You’re allowed to rewrite the script."

Tourism can be a blessing for the economy of many cities around the world, but it often comes at a price. Destinations like Venice and Bali are iconic for a reason — they’re unique, breathtaking places that lure travelers from around the globe. But when a travel destination becomes too popular, it risks losing its charm and overcrowding can strain infrastructure, inflate costs for locals, and disrupt the peace and quiet of small, serene towns.

Here are 12 destinations that have struggled with overtourism. The good news? Many are implementing smart strategies to balance tourism with sustainability. Planning to visit? Consider booking during the off-season for a more authentic and enjoyable experience or try these hidden gems.

Venice, Italy

Cruise ships and swarms of tourists have overwhelmed this picturesque city, leading to overcrowded canals, damaged infrastructure, and skyrocketing prices. The local population is dwindling as Venetians leave due to the city’s unsustainable tourism boom. Last spring, in an effort to manage the influx, the city put into effect an entry fee for day-trippers and has limited cruise ships docking its shores.

Oleksandr P

Bali, Indonesia

Once an idyllic paradise, Bali now suffers from traffic congestion, environmental degradation, and overcrowded beaches. The island’s resources are strained under the weight of mass tourism, but there are efforts underway to promote sustainability like putting a moratorium on new hotels.

Willian Justen de Vasconcellos

Machu Picchu, Peru

Overtourism has led to erosion and damage to this ancient Incan citadel. A quota system and mandatory guides are helping preserve this popular South American destination.

Darren Lawrence

Tulum, Mexico

Once a tranquil paradise known for its pristine beaches, ancient Mayan ruins, and eco-chic vibe, Tulum has become a cautionary tale of overtourism. The surge in popularity, fueled by Instagram-worthy scenery, has brought overcrowding, environmental strain, and rising costs. The Guardianreported that locals are being pushed out by developers and despite the thinking that tourism helps local communities, poverty nearly doubled between 2015 and 2020. Local ecosystems, including fragile mangroves and coral reefs, are threatened by unchecked construction and pollution too. The local ruins have implemented stricter rules like no food or drink to limit trash and environmental impact from tourists.

Jimmy Teoh

Santorini, Greece

Instagram fame has turned this once-serene island into a tourist hotspot. Narrow streets are perpetually clogged, and locals are struggling with soaring costs of living due to tourism demand. The government has since capped the number of daily cruise ship visitors to keep overtourism at bay.

Chait Goli

Cinque Terre, Italy

Known for its colorful cliffside villages and breathtaking coastal views, these once-quiet fishing towns now see millions of visitors annually, way more than they can handle. To combat issues like congestion and cruise ships, local authorities have introduced visitor caps and encourage sustainable travel to protect Cinque Terre’s charm.

Rudy Kirchner

Reykjavík, Iceland

Is there anyone not going to Iceland these days? A small country with breathtaking landscapes, Iceland has been overwhelmed by tourists flocking to Instagram-famous sites like the Blue Lagoon and Diamond Beach. It's best to travel during the off season (November to April) and travel to lesser known spots like the Sturlungalaug hot spring.

youseflns

Maya Bay, Thailand (Phi Phi Islands)

This iconic beach, popularized by the DiCaprio film The Beach, suffered ecological devastation from hordes of visitors and anchored boats. Coral reefs were destroyed, and the beach was closed for years to allow recovery. It has since reopened after a huge revitalization project, but they have introduced visitor caps.

Pixabay

Kyoto, Japan

Traditionally quiet streets of this ancient capital city now teem with tourists during peak season. An increase in litter from tourists has required the city to install more trash bins to handle the crowds, and peaceful geishas are often chased down for photos. To mitigate the problem, Kyoto is considering running special buses to popular sites to reduce overcrowding, and temples and shrines are encouraging visitors to come early in the morning.

Prabin Sunar

Mount Everest, Nepal

The ultimate challenge for adventurers, Mount Everest has experienced overcrowding on the slopes and at base camps, leading to dangerous conditions, with litter and human waste piling up on the mountain. Permits are now harder to get, and stricter regulations for climbers are being enforced.

Mateusz Popek

Dubrovnik, Croatia

The Game of Thrones effect brought an influx of fans to this medieval city. Overcrowded streets and cruise ship arrivals have made it difficult to appreciate its beauty. The local government is taking steps to limit daily visitors and impose stricter cruise ship regulations.

Helena I

Lisbon, Portugal

Short-term rentals dominate the housing market now, thanks to affordable flights and the digital nomad craze. This has led to skyrocketing rents and displaced locals. Historic neighborhoods are inundated with tourists, making them less charming too. Everything from public transport to waste management struggles to keep pace with the influx. I went in December and it still felt a bit like Disneyland. Douro Valley and Madeira might be more favorable destinations any time of year.

Did you leave your family Thanksgiving dinner last year feeling like you were the one who got carved up and digested? You weren't alone. In an increasingly polarized sociological climate, family events where opinions differ can feel fraught with high stakes and conflicting moral obligations. And if you're already dreading Thanksgiving because all of the brawlin' that's sure to go down, you might be considering opting out of the festivities entirely.

In our Teach Me Something New podcast, Alexandra Carter, Columbia law professor and mediation expert, talks to Brit and Anj about the powers of persuasion to get the results you want in a conversation. The key to the Thanksgiving political discussion? Listening, asking open questions, and finding some common ground.

Here's what you can do to make it through Thanksgiving when your relatives just keep being problematic and things get awkward...

"I might say something like, 'I hear that you're concerned about national security and that's what led me to have this viewpoint.' So sometimes using a little bit of focusing on what you have in common can help you to have a civil conversation and not have anybody throwing mashed potatoes across the table," says Carter.

Here are more expert-backed tips for navigating the holiday awkwardness, even if it's just via Zoom. Make stuffing your face great again this Thanksgiving by implementing our seven-step plan.

Askar Abayev

1. Choose your battles ahead of time.

You're not going to change everyone's opinion about all of the things over the course of a meal and a football game. You might want to show up ready for a duel of words with your Facebook-meme-king cousin, but that's just going to put your opinionated family member on the offensive from the moment you walk in. Decide ahead of time if there's one issue that you really cannot keep your mouth shut about if it comes up, and have two or three talking points ready that clarify your position on that topic. If your hot button does get pushed, your talking points will help you keep from making things personal.

2. Confer with the host.

If you feel comfortable with the person that's organizing or hosting Thanksgiving, speak to him or her in advance about how you can be on Team Keep the Peace. Most people aren't keen on a political brouhaha breaking out around their dinner table, so they'll probably be relieved to hear that you're on board and willing to help make the day go smoothly for everyone. Brainstorm some ideas about seating arrangements or wholesome activities to fill the idle family time that can lead to trading barbs.

3. Make it a game.

Caitlin Bergstein, a Boston-based matchmaker and relationship expert for Three Day Rule, suggests a fun twist on the swear jar concept. “If your family is up for the challenge, you can even make it a game. Each time someone mentions something political, they have to put a dollar in a jar (or take a drink, depending on how your family celebrates the holiday). At the end of the night, that cash can be put aside for the next family get together!"

4. Have a moment of silence.

Sometimes the idea of a quiet table can be intimidating (all those chewing noises!), but encouraging a moment of reflection among your holiday guests can actually be transformative. Whether you observe several seconds of silence in honor of relatives you've lost, as a way to silently acknowledge your individual blessings, or as an act of prayer or meditation, you've hopefully brought the room back to focus on each other's company and the gift that it is to be together.

5. Be an active listener.

If your one doggedlypersistent aunt can't let go of her obsession with the latest political scandal, reconsider what she's actually trying to tell you. Chances are, it's not just about what she saw on the news. “Assume that your polarizing relative actually probably just wants to connect, feel respected, and reduce their own anxiety about holiday gatherings, and interpret even difficult behavior as such," advises Mary Fisher, a Salt Lake City psychotherapist who specializes in family relationships. “Express the desire to connect while redirecting the conversation," Fisher recommends. Emphasize the fact that you're interested in protecting the time your family spends together. That can help soften the blow when you ask to instead hear them share a family memory or talk about a hobby you both share.

6. Disengage.

Remember that if angry words or offensive language start flying at you across the sweet potato pie, you don't have to respond. Have a script in mind to use, something like, “While I hear where you're coming from, I don't share your opinion, and I'm done talking about it today." Convey the message that you're quite clear on the matter being discussed, and you're not going to take the bait. You may have to repeat yourself several times, or you may choose to remain silent until things cool down around you. Either one is okay.

7. Duck out early.

If you feel like you have to retreat from the situation entirely, do it. One of the best things about being an adult is leaving when you want to leave. You don't have to subject yourself, your spouse, or your family to any kind of dialogue that is insulting, bigoted, or aggressive. Fisher shares these words of advice: “While we might think that the holidays are the time to resolve differences, they are actually the time to affirm and nurture connection, which can be an uphill battle with politically polarizing relatives." If you don't feel like a connection is being nurtured and the environment is not good for you to be in, say goodbye and make a break for it.

Christmas cookie decorating is holiday tradition for us here at B+C, so we were so stoked to find this recipe for paleo cookies that adds a healthy twist to this classic holiday dessert. These sweet treats will shine among the rest of your Christmastime tablescape, and they are super easy to make. Plus, they'll pair well with just about any Christmas dessert. Just combine your paleo-friendly ingredients to prep the dough, let it sit overnight, then bake for ten minutes! The best part about this recipe is of course, all of the fun holiday-time shapes you can cut. Consider this recipe your go-to for healthy cookies, though, since you can make them year-round in any shape you like. Let's get to decorating!

Ingredients for Paleo Christmas Cookies

Brit + Co

For the cookies:

  • 1/2 cup grass-fed salted butter, softened
  • 6 tablespoons raw honey
  • 2 eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon almond extract
  • 3 cups almond flour
  • 1/2 cup coconut flour
  • 1/2 teaspoon baking soda

For the frosting:

  • 6 tablespoons coconut butter or coconut manna
  • 1/4 cup cacao butter
  • 1-2 tablespoons honey
  • Plant-based food coloring
  • Vegetable-dyed sprinkles, for topping*
* Look for vegetable and fruit-dyed food coloring and sprinkles in natural grocery stores or online, and avoid artificial colors to keep these cookies Paleo friendly!

How to Make Paleo Christmas Cookies

Brit + Co

  1. Add the softened butter and honey to a large mixing bowl. Cream the mixture together using a handheld mixer until it is smooth. Add in the eggs, vanilla extract, and almond extract and whisk until they are well combined. Pour in the almond flour, coconut flour, and baking soda, and continue mixing until the batter has come together smoothly.
  2. Separate the dough into two, and place each one on top of a piece of plastic wrap. Roll each dough into a ball, then flatten to a thick disk, cover completely with the plastic wrap, and place in the refrigerator to firm up for at least 2 hours or overnight.
  3. Preheat the oven to 350 degrees F. Remove one of the dough discs from the refrigerator, unwrap the plastic and place the dough on top of a piece of parchment paper, then top it with another piece of parchment paper. Use a roller to flatten out the dough to about 1/4 to 1/2 of an inch thick. Work quickly with your favorite Christmas cookie cutters, and use a thin spatula to lift the cut cookies onto a baking sheet lined with parchment paper.
  4. Bake the cookies in the oven for 10 minutes. Let them cool for a few minutes, then place on a wire rack for further cooling. Gather the leftover scraps back into a ball in the plastic wrap or parchment paper and place it back in the refrigerator, while working with the other piece of dough. Do this in batches to keep the dough from getting too warm and so you don’t overcrowd the baking sheet.
  5. While the batches of cookies are baking, use a small saucepan to lightly melt the coconut butter and cacao butter together over low heat on the stovetop. Remove the pan from the heat when the ingredients have just melted together. Stir in the desired amount of honey, then set aside to cool and thicken up slightly. If you are using food coloring, add in the desired amount into the frosting mixture (1-2 teaspoons of green or red should do the trick). If you plan on only using white frosting, only use a small amount of honey, as it can make the frosting an off-white or light brown color.
  6. After the cookies have completely cooled, decorate them with the frosting and sprinkles as desired. If you don’t have any professional piping tools, an easy fix is to place the frosting in a plastic sandwich bag and remove all the air when sealing the top. Cut a tiny tip off one corner of the plastic bag, then gently squeeze and pipe over the cookies. Use one plastic bag or piping bag for each color of frosting. Top with corresponding sprinkles and enjoy!
