Why Do I Keep Overthinking Everything?

It’s December in the West Hills, and you’re trying to plan one nice holiday outing for the family. Simple enough — except now you’re three days deep in it. Should you do the Nutcracker at the Benedum? A Musical Christmas Carol at the Byham? The Holiday Pops at Heinz Hall? Which night, so the kids aren’t melting down by intermission? What about parking, and traffic coming back through the tunnels, and whether your sister will be hurt if you go without her, and whether you’ve picked the wrong show entirely, and whether anyone will actually have a good time?

By the time you’ve run every scenario, the fun has quietly drained out of a thing that was supposed to be fun. And a small, tired voice asks: why do I do this to myself? As a therapist here in Robinson, I hear that question constantly — so let’s actually answer it.

What Overthinking Really Is

“Overthinking” usually comes in two flavors, and most of us do both. There’s rumination — looping on the past, replaying a conversation, cringing at something you said, re-litigating a decision you already made. And there’s worry — rehearsing the future, running the what-ifs, pre-living every way a thing could go wrong. Different directions, same engine: a mind trying to think its way into feeling safe or in control.

That’s the key insight I want you to have. Overthinking isn’t a personality quirk or a sign you’re “too much.” It’s your brain doing a job it believes is protective — trying to prevent a bad outcome, resolve an uncertainty, or make sure no one is upset with you. The intention underneath it is usually care. The method just doesn’t work.

Why Your Brain Keeps Doing It

Overthinking is sneaky because it feels like problem-solving. Real problem-solving reaches a conclusion and stops. Overthinking circles the same ground and never lands — but it produces just enough sensation of “doing something” that your brain keeps reaching for it. There’s also a hit of false reassurance: if I just think about every angle, maybe I can keep anything bad from happening. The trouble is that certainty isn’t actually available, so the mind never gets the all-clear it’s waiting for, and the loop runs again.

Underneath a lot of overthinking is one hard thing: difficulty tolerating uncertainty. Not knowing feels unbearable, so the mind tries to resolve the unresolvable — and exhausts you in the attempt.

It Steals the Thing You Were Trying to Protect

Here’s the cruel part. Even a straightforward trip out of the gleaming new terminal at Pittsburgh International becomes a project — did I leave enough time, what if security’s backed up, what if I forgot something, what if, what if — until you’re standing in one of the nicest airports in the country, missing it entirely because your mind is three hours into the future. You finally get to the Nutcracker, and you’re so busy managing everyone’s experience that you don’t have one of your own.

Overthinking promises to protect your life and then quietly spends it. The present moment — the one you were actually trying to make nice — is the thing it keeps taking.

When Overthinking Is Anxiety

I want to name this gently but clearly: persistent rumination, chronic worry, and intolerance of uncertainty are core features of anxiety. So if your mind won’t switch off, if you lie awake rewriting the day, if small decisions feel genuinely hard and big ones feel impossible — that’s not you being dramatic or weak. That’s an anxious nervous system doing what anxious nervous systems do. And that matters, because it means this is a treatable pattern, not a fixed trait. “I’m just an overthinker” is a description, not a life sentence.

What Actually Helps

You can’t usually stop overthinking by telling yourself to stop — if that worked, you’d have done it by now. What tends to help is different and learnable:

• Catching the loop. Learning to notice “oh, I’m ruminating” is itself a skill, and naming it takes some of its power.
• Telling problem-solving from spinning. If thinking about it will change something, think — then act. If it won’t, that’s the loop, and the work is learning to let it go unfinished.
• Building a tolerance for uncertainty. Much of therapy is gently practicing “I don’t know, and I can be okay anyway” — which is the actual cure for a mind demanding guarantees that don’t exist.
• Letting “good enough” be good enough. Any of those three holiday shows will make a lovely memory. The perfect choice isn’t the goal; a present, un-exhausted you is.
• Self-compassion instead of self-criticism, because beating yourself up for overthinking is just… more overthinking.

In my work I lean on approaches like CBT and ACT to do exactly this — interrupting the patterns, loosening the grip of the what-ifs, and helping people get their evenings, their sleep, and their holidays back.

Let’s Talk

If your mind runs you ragged over things that are supposed to be simple, you don’t have to keep white-knuckling through it — and you definitely don’t have to be “bad at relaxing” forever. I see clients at CPA Counseling’s Robinson office, just minutes from the airport in Pittsburgh’s West Hills, and by telehealth across Pennsylvania. Your mind can learn to let the moment be enough.
