Why do i keep overthinking everything?

"Oh God...WHY did I say that?"

Or maybe it's:

"What if this headache is actually something serious?"

"Did I send that email too aggressively?"

"I should've checked my work one more time."

"They're probably mad at me."

"What if I made the wrong decision?"

Overthinking is a bit of an overachiever. It doesn't really care what the topic is.

It'll happily invite itself to your work meetings, your doctor appointments, a text conversation, even a perfectly normal dinner with friends. Before you know it, it’s keeping you up at midnight, analyzing every detail, predicting worst-case scenarios, or trying to answer questions that don't actually have clear answers.

But the harder you think, the less certain you feel.

So...why do we do this?

Imagine Your Brain Is a Road Trip

In an ideal world, our brains would be like a peaceful road trip. Windows down. Good music. Maybe a snack stop. But we’ve got a rag-tag crew running the show, and sometimes, things take a turn for the worst.

Meet the Toddler in the backseat. It doesn't understand context, nuance, or the concept of time. When a text says"We need to talk," the toddler doesn't think, "Oh, maybe they want to discuss weekend plans." Instead, it screams, "WE ARE ALL GOING TO DIE! PREPARE FOR IMPACT!" It kicks the back of our seat, throws its sippy cup, and triggers a full-blown meltdown over a single stray crumb of uncertainty.

In that moment, the Car panics and assumes it is driving off a cliff. Suddenly, the check engine light flashes (hello, chest tightness and heart palpitations). The exhaust starts smoking (our breathing gets shallow and fast), and the engine makes mysterious noises (that sinking, butterfly feeling in your stomach).

Meanwhile, the logical Driver who planned the trip and mapped out all the pit stops is suddenly gripping onto the steering wheel for dear life. It’s trying to navigate heavy traffic while the Toddler shrieks and the Car dashboard lights up like a Christmas tree. Of course, the Driver looks around and thinks, “There must be a problem." So, it naturally tries to solve it.

"Maybe if I replay the conversation..."

"Maybe if I think through every possible outcome..."

"Maybe if I analyze it just one more time..."

The Driver’s goal isn’t to make us miserable. It's trying to make everyone in the car feel safe. The problem is that it's attempting to solve uncertainty. And uncertainty isn't a puzzle we can think our way out of.

Why Overthinking Keeps Going

Every new "what if" feels like another chance to achieve certainty. But each answer creates another question.

"Okay...but what if they actually meant..."

"Yeah, but what if the doctor missed something?"

"What if I made the wrong choice?"

The Toddler hears all of these possibilities and thinks, “See? I knew we should panic!"

Around and around everyone goes.

If this sounds familiar, you're not broken. Your brain is doing exactly what it was designed to do: notice potential danger and try to protect you. It just gets a little...overenthusiastic sometimes.

Two Things That Actually Help

Notice I didn't say, "Just stop overthinking." If you've ever tried that, you know it's about as effective as telling a real toddler to calm down. Instead, try this.

Ask yourself who's talking.

Is this the Driver trying to solve a real problem? Or, is the Toddler reacting to uncertainty? Simply noticing the difference can help you step out of autopilot.

Let uncertainty ride along.

Instead of demanding an answer, try saying, "Maybe they're upset. Maybe they're going through something. I honestly don't know yet." The goal isn't to convince yourself everything is okay. It's to practice not needing immediate certainty. Ironically, that's often when your nervous system starts settling on its own.

Where Therapy Comes In

Therapy isn't about getting rid of the Toddler (if only). It's about helping the Driver recognize when the toddler tries to switch gears on us. Over time, you learn how to respond differently. Instead of spending hours replaying conversations, predicting disasters, or chasing certainty, you build confidence that you can handle uncertainty, even when it feels uncomfortable.

The Toddler will probably always have opinions. But eventually, the Driver learns to smile in the rearview mirror and say, "Thanks for your input. I've got the wheel."
