I’ve been thinking a lot lately about friendship. Not the surface-level kind where you follow each other on Instagram and occasionally like a post, but real, meaningful friendship.

The kind where someone actually knows what’s going on in your life.

Here’s what’s interesting: I notice a pattern among people who struggle to maintain close friendships in adulthood. It’s not that they’re antisocial or broken in some way.

It’s that something happened earlier, back when they were still figuring out how relationships work.

Research backs this up too. Studies show that people who had no friends in childhood are roughly twice as likely to experience psychological difficulties in young adulthood compared to those who had at least one close friend.

The experiences that shape our ability to connect aren’t always dramatic. Sometimes they’re subtle, barely noticeable at the time. But they compound over years, creating patterns that follow us into our thirties and beyond.

Let’s dig into eight childhood experiences that often show up in the histories of adults who find themselves without a solid friend group.

1) They moved around frequently during their formative years

Think about what happens when you’re constantly starting over. You’re the new kid again and again, always on the outside looking in at established friend groups.

I had a friend in college who’d been to seven different schools by the time he graduated high school. He was charming and funny, but he had this interesting habit of keeping everyone at a certain distance.

When I asked him about it once, he said something that stuck with me: “What’s the point of getting too attached when you’re just going to have to say goodbye anyway?”

That mindset made sense for him as a kid. It was protective. But it followed him into adulthood, where relationships don’t have built-in expiration dates.

When you learn early on that connections are temporary, you might stop investing in them altogether. You develop this sort of emotional efficiency where you don’t waste energy on bonds that feel inherently fragile.

2) They experienced emotional neglect at home

Here’s something I learned from therapy: if you didn’t see healthy emotional expression modeled at home, you might not know how to do it yourself.

When kids grow up in environments where communication is unhealthy or even scary, it deeply influences how they form and maintain friendships as adults.

My parents divorced when I was 22, and looking back, I realize there wasn’t a lot of emotional openness in our house growing up. My dad came home from construction jobs in his work clothes and cooked simple dinners. My mom worked doubles as a nurse. There wasn’t much space for feelings.

I didn’t realize how that affected me until I was trying to navigate adult friendships and found myself shutting down whenever conversations got too personal. I’d learned that emotions were something you dealt with privately, not something you shared.

When you don’t learn emotional literacy as a kid, adult friendships can feel like you’re trying to speak a language everyone else seems fluent in.

3) They were bullied or consistently rejected by peers

The playground can be brutal. Kids who face persistent bullying or rejection often carry those wounds well into adulthood, even if they don’t realize it.

Studies indicate that childhood traumas like bullying are more likely to have lasting impacts on our psyche. Individuals who experienced bullying as children are more prone to adult paranoia.

What happens is you develop a kind of social hypervigilance. You’re always scanning for signs that you’re about to be rejected again. It’s exhausting, and ironically, it can create the very distance you’re trying to avoid.

I’ve watched this play out in my book club, where one guy consistently misreads neutral social cues as rejection. Someone can’t make it to a meetup and he immediately assumes it’s personal, that he said something wrong last time.

4) They learned to rely primarily on themselves

Some kids become self-sufficient out of necessity. Maybe their parents were overwhelmed with work or other responsibilities. Maybe they had younger siblings they needed to care for.

I helped put my youngest sister through college with savings from my corporate job. Growing up working class, I watched my mom stretch every paycheck and learned early that you couldn’t always count on others being available.

That self-reliance served me well in many ways. But there’s a flip side. Children who experience early adversity often struggle with interpersonal interactions, and these social difficulties can persist far beyond childhood.

When you learn that asking for help is unreliable or burdensome, you stop doing it. You become the person who always says “I’m fine” even when you’re not. And friendship requires some vulnerability, some admission that you need people.

5) They didn’t have opportunities to practice social skills

Some researchers argue that without the opportunities friendships provide for collaboration and intimacy, children fail to develop the social skills necessary for later successful adult relationships.

Maybe they were homeschooled without much peer interaction. Maybe they were shy and their parents didn’t push them into social activities. Maybe they spent most of their free time alone.

Whatever the reason, they missed out on those crucial trial-and-error experiences where you learn things like conflict resolution, compromise, and reading social cues.

It’s like trying to learn a sport without ever practicing. You might understand the rules intellectually, but you’re awkward in execution. You don’t have the muscle memory that comes from repetition.

One thing I’ve noticed at my recreational basketball league is how some guys are clearly still learning the unspoken rules of team dynamics at 36. They hog the ball or don’t pass when they should because they never developed that intuition in childhood.

6) They witnessed unhealthy relationships as their primary model

Kids are sponges. They absorb the relationship patterns they see around them, especially from their parents.

If you grew up watching relationships characterized by conflict, manipulation, or constant instability, that becomes your blueprint. You might not even realize you’re recreating those patterns until someone points it out.

I recently read “Laughing in the Face of Chaos” by Rudá Iandê, and one of his insights really struck me: “Being human means inevitably disappointing and hurting others, and the sooner you accept this reality, the easier it becomes to navigate life’s challenges.”

That hit differently for me because I’d spent years avoiding conflict in friendships, thinking any disagreement meant the relationship was doomed. I’d learned from my parents’ divorce that conflict equals failure, rather than seeing it as a normal part of any relationship.

7) They experienced significant loss or trauma early on

Losing a parent, experiencing abuse, or going through other significant trauma changes how you view relationships. It makes sense, right? If your world has been fundamentally unsafe or unpredictable, you’re going to be cautious about getting too close to people.

Trauma history can lead to difficulties with trust, which is the cornerstone of any healthy relationship, including friendships.

What I’ve learned through my own therapy is that trauma responses aren’t character flaws. They’re adaptations. The problem is that adaptations that helped you survive childhood might actively hurt you in adulthood.

Someone who learned to never trust anyone as a protective measure might find themselves unable to form the deep connections they actually crave as an adult.

8) They were raised in an environment that devalued friendship

Some families treat friendship as frivolous. They emphasize achievement, work, or family to the exclusion of peer relationships.

I saw this in corporate America throughout my twenties. There were people who’d clearly been raised to prioritize career above all else. They didn’t know how to just hang out without it being networking. Every relationship had to serve a purpose.

When I left my six-figure job at 29 to pursue a startup, I lost most of my work friendships. They disappeared almost immediately, and I realized they were transactional all along. But some people never learn to form any other kind.

If you grew up hearing that friends are a distraction from what really matters, you might struggle to prioritize those relationships in adulthood, even when you consciously want them.

Rounding things off

Look, having few close friends in adulthood doesn’t mean you’re defective. It means you learned certain patterns early on, and those patterns stuck around longer than they should have.

The research is pretty clear: childhood friendships are foundational for building cognitive, social, and emotional skills that we carry into adulthood, and positive early friendships are linked to lower rates of loneliness and depression.

But here’s the thing about patterns: they can be interrupted. They can be relearned.

I’m 36 now, and I still catch myself defaulting to old habits. I still have that impulse to handle everything alone, to not bother anyone with my problems. But I’m also part of a group chat with six friends where we share mundane daily updates, and I make time for my Thursday night gaming sessions even when I’m busy.

If you recognize yourself in any of these experiences, start small. Pick one pattern you want to change. Maybe it’s reaching out when you’re struggling instead of defaulting to “I’m fine.” Maybe it’s saying yes to social invitations even when it feels uncomfortable.

Friendship in adulthood requires intention in a way it didn’t when we were kids. But it’s also more rewarding because you’re choosing it consciously, not just because you sat next to someone in homeroom.

The experiences that shaped you don’t have to define you forever. That’s the whole point of awareness.
