I had a breakthrough in therapy this week and almost fainted.

This has happened just a handful of times before. A revelation comes clear and suddenly it feels like I’m on an elevator dropping down too fast, I go grey around the edges, and then I start crying. Once I threw up in my therapist’s wastebasket, but that’s another story.

Let me tell you about my uncle.

My uncle was fifteen when I was born, which made him feel more like an older brother than an uncle. He was my mother’s half-brother, and according to family stories, he was a delicious baby (in my Jewish family, the best compliments describe you as edible) and the cutest little boy. As a man, he was big — physically, but also with a huge personality. He told stories he couldn’t finish because he’d start laughing before he got to the punchline. What he wanted from life was simple. He wanted to drive a cab. Watch the Rangers and the Yankees. Hang out with his friends. Spend time with his kids.

What he got instead was a wife who wanted a lawyer for a husband, and an expensive life.

And because he had his own weaknesses and fears, just like everyone, he became a lawyer. And in trying to be what she demanded he be, his worst impulses took over. Gambling. Stealing. Borrowing money from the sort of people who don’t work for a bank. And sudden, terrifying rages. He had his own particular darkness, is what I’m saying. And at the end, it killed him.

When I was little, he would sometimes be at my grandma’s house when I got home from school. My mother worked. My grandma took care of me. And if I was lucky, my uncle was there too, stretched out on the convertible sofa in the room that used to be his, and we’d watch cartoons together. Superman. Super Friends. He’d read me the comics from the newspaper, and he’d play me comedy albums — Allan Sherman, Bob Newhart, George Carlin, Richard Pryor.

I adored him. He was my uncle, brother, and buddy, more like another kid than one of the grownups. He also scared me and hurt me, over and over.

He turned me into a sentinel of my own heart.

I have visceral memories of standing in the doorway of family gatherings before I walked in. A house. A restaurant full of cousins and noise. It didn’t matter where. I would stand at the threshold and hold my breath. I’d scan the room until I found him. Was he laughing? Was he quiet in the wrong way? Was he in one of his moods? What kind of day was this going to be?

I was always checking. Always assessing. Always preparing for whatever version of him had shown up.

Back to this week’s therapy. Here is what I realized: I am still standing in doorways, hoping for the best, anticipating the worst, reading the room before I decide how I’m going to show up.

At work, this looks like a twinge of nausea before opening my laptop in the morning. An anxious wave walking into the office. A flinch as I join a meeting, read an email, check my phone. All these years later, there is still a part of me that believes it is my job — one only I can do — to determine what kind of day this is going to be before it begins. To scan for threats. To decode the energy in the room and adjust accordingly. To buffer. To absorb.

It plays out in my personal life too, intensified over the past two years, when my husband went through a severe mental health crisis that eventually required psychiatric hospitalization. Every day when I came home from work, I felt that same clammy dread before I opened the door. What would I find? Would he be okay? Would he still be there?

Different doors. Same kid standing on the threshold, holding her breath.

I’ve always beat myself up for being so anxious, so cautious, so watchful and agreeable, often to my own detriment. Turns out, my fear and people pleasing wasn’t irrational, it was a survival skill. Hypervigilance isn’t a personality flaw or a weakness. It’s an adaptation. Children who grow up around unpredictability become experts at reading a room because they have to. You learn to notice everything. Changes in tone. The set of someone’s jaw. A laugh that’s a little too loud or a little too forced. You learn to anticipate problems before they arrive, because anticipating is the only control you have. It’s one thing to know this intellectually. It is quite another to feel it click together inside your own body on a Friday afternoon, the child you were reaching to grab the hand of the woman you’ve become and pointing, “See. There. This is why. I am so tired. Can we stop?”

And once you see yourself doing it and understand why, it’s everything and everywhere. This one is almost embarrassing, but this morning I braced — actually braced, the same tightening in my chest — before opening a text from a close friend. Someone I love. Someone who has never once frightened me. My nervous system doesn’t care. It’s running the same old scan, on alert, finding nothing and checking again anyway.

I’ve built real things from this vigilance. It made me intensely observant. It made me deeply empathetic. It made me a skilled caregiver and advocate. There is, genuinely, a gift buried inside the pain.

It’s a gift I’d like to return, but unfortunately, no backsies on this one.

When you’re always bracing for impact, it’s hard to relax into anything. It’s hard to trust that a quiet moment is actually quiet. It’s hard to let yourself be seen, because being seen feels like exposure, and exposure has always felt like risk.

What I’m learning now — somehow still learning, despite being in therapy for so much of my adult life — is that the little girl I was, standing in doorways, was right to pay attention. She kept herself safe the only way she knew how.

I think about my uncle on that convertible couch, reading me the comics, laughing before he got to the punchline. I think about him before he fell to ruins, trying and failing to be someone he simply wasn’t.

And I know it’s time to walk through — fears and failures and quirks and cringe be damned.
