Why Your Brain Won't Stop: Understanding the Anxiety Spiral

We've all been there: lying in bed at 3am while your brain helpfully replays that weird thing you said in a meeting three years ago. Or scrolling through worst-case scenarios like a Netflix queue of doom.

The anxiety spiral is real, and it's exhausting. But here's the thing—your brain isn't broken. It's actually doing exactly what it's designed to do: protect you from danger. The problem is, it can't always tell the difference between a saber-toothed tiger and an unanswered email.

Anxiety spirals rarely stay "just thoughts." Once your threat-detection system kicks in, your body starts stacking evidence: faster heart rate, shallow breathing, that tight-band feeling in your chest. Your brain, trying to be helpful, treats those sensations like proof that something is wrong—so it goes looking for a story to match the feeling. The story makes the feeling worse. The feeling makes the story more believable. That loop can run for minutes or hours, and it can start from something as small as a delayed text.

This isn't you being dramatic. It's a nervous system doing pattern completion under stress. The spiral gets louder when you're tired, hungry, overstimulated, or already stretched thin—basically, a normal Tuesday in New York.

If your dread shows up like clockwork on Sunday nights, you're not alone—Sunday scaries is one of the most common shapes this takes. If you're also running on fumes from constantly catching up with yourself, that overlap shows up a lot in what I call executive functioning struggles.

Here's how I explain it in my office (and honestly, in my own head on a bad night): there's a part of you that's always scanning for threats. When it finds one—real or imagined—your body kicks into fight-or-flight. Blood pressure rises, muscles tense, and the part of you that's good at thinking straight basically goes offline.

This was great for our ancestors running from predators. Less great when the "threat" is wondering if your coworker's "fine" in that email meant they're actually mad at you.

If you also have ADHD, anxiety can feel even more intense—your brain is already working overtime, and adding constant threat-scanning to the mix is exhausting.

2. Ground yourself: The 5-4-3-2-1 technique works. Name 5 things you can see, 4 you can hear, 3 you can touch, 2 you can smell, 1 you can taste.

3. Question the thought: Is this thought helpful? Is it based on facts or feelings? What would I tell a friend thinking this?

4. Move your body: Anxiety is physical. A short walk, some stretching, or even shaking out your hands can help discharge the nervous energy.

The goal isn't to never feel anxious—that's not realistic. It's to build a different relationship with anxiety, one where it doesn't run the show. For more practical techniques, check out my guide on how to stop an anxiety spiral.

"Your brain isn't broken. It's doing exactly what it's designed to do."

If you notice anxiety showing up in the same situations over and over—in relationships, at work, in your inner monologue—that's worth paying attention to. Sometimes anxiety is a signal pointing to deeper patterns that therapy can help untangle.

It's the Slack message you reread until the tone shifts in your head. It's lying down "for ten minutes" and suddenly you're replaying a conversation from 2019, adding new dialogue where you finally said the perfect thing. It's checking your email at 11pm even though you promised yourself you wouldn't, because your brain treats "unread" like a loose wire touching metal.

It's also the quieter version: going quiet in a relationship because you're trying to pre-manage someone else's reaction, or feeling your stomach drop when your calendar pings—before you've even read what the meeting is about. It's walking past a group of coworkers laughing and assuming the joke is you, even when you have zero evidence. It's the Sunday version too: the day isn't over yet and you're already doing emotional math about Monday like it's a verdict.

The content changes. The mechanism is the same: your system is trying to solve a future problem with present-moment panic.

Why does my anxiety feel physical if nothing is "really" wrong?

Because your body doesn't negotiate with context the way your mind does. Fight-or-flight is a whole-body event: muscles brace, digestion downshifts, attention narrows. Once that machinery is on, it can feel like evidence—even when the trigger is ambiguous. Naming it ("this is adrenaline, not a verdict") doesn't fix everything, but it can take the story down a notch so you're not treating sensations like facts.

Is anxiety always about fear of the future?

Often, yes—but "future" can mean five seconds from now. Anxiety can also latch onto the past (embarrassment replays) or the present (hypervigilance in a room). What ties the versions together is threat-scanning: your brain is trying to reduce uncertainty by running simulations. The problem is the simulations don't come with an off-switch—and the more you argue with them at 2am, the more fuel you add.

When is anxiety a signal to get support vs. something to manage on my own?

If it's shrinking your life—avoidance, sleep wrecked, relationships strained, work suffering—or if the spiral is frequent enough that you're organizing your week around preventing triggers, that's worth taking seriously. Self-help tools help some people some of the time; they aren't a moral failing when they're not enough. If you're weighing options, you can read how I work on the services page, and we can talk candidly in a consult about what would actually help for you.

If anxiety is running the show and you're tired of it, I offer a free 15-minute consultation to talk about what you're experiencing. No pressure—just an honest conversation about whether therapy might help.
