When Worry Takes Over: Understanding Overthinking
"Did I say the wrong thing?"
"What if something goes wrong?"
"Maybe I should have handled it differently."
Most of us have had thoughts like these. Thinking is useful; it helps us solve problems, plan ahead, and make sense of hard experiences.
But sometimes it can be a roadblock. You replay the same conversation for ten times, picture how things could have gone differently, or keep looking for a certainty that isn't there. This is what people usually mean by overthinking.
What Is Overthinking?
"Overthinking" isn't a clinical diagnosis. It's an everyday word for repetitive thinking that's hard to switch off. It can look like:
going over past conversations or decisions again and again
worrying about what might happen
imagining one worst case after another
second-guessing whether you made the right choice
looking for reassurance, but never quite feeling reassured
Some of this is fine, can even be helpful. Planning and problem-solving are part of daily life. The trouble starts when thinking goes in circles and doesn't lead to a decision, or an action.
When Thinking Becomes a Cycle
For many people, overthinking and anxiety go hand in hand. An anxious mind tries to get ahead of whatever could go wrong, and running through every possibility can bring a brief sense of control.
But we can't fully remove uncertainty. The harder we try to think our way to certainty, the more possibilities the mind produces:
"What if…?" → "But what if…?" → "Maybe I missed something…"
At some point, the thinking itself becomes the thing that hurts.
That doesn't necessarily mean you have an anxiety disorder. Anxiety is a normal response to uncertainty, change, and perceived threat. But if worry is persistent, hard to control, very distressing, or getting in the way of daily life, it's worth looking at more closely with a professional.
Why Do We Get Stuck?
There's no single answer. For some people, worrying feels like preparing. For others, it can be tied to perfectionism, fear of making mistakes, a low tolerance for uncertainty, or a strong need not to let others down.
A trauma-informed lens adds another question: did constantly anticipating problems once protect you? In some environments, staying alert to other people's reactions, or to what might happen next, really did help someone feel safer.
That doesn't mean overthinking always comes from trauma. It means the pattern may have a purpose, and that purpose is worth understanding before we try to get rid of it.
A Person-Centred Perspective
Instead of only asking "How do I stop overthinking?", a counselling conversation might also ask:
"What is my mind trying to protect me from?"
Maybe it's rejection, a mistake, losing a relationship, or just not knowing. Once you can see what the thinking is for, you have more room to respond differently.
The goal isn't to stop caring, planning, or thinking things through. The goal is to become more flexible: to notice when thinking is helping and when it's keeping you stuck.
When Should You Seek Support?
Overthinking now and then is part of being human. But consider reaching out if repetitive worry takes up a lot of your time, affects your sleep or concentration, strains your relationships, or leaves you constantly on edge.
Approaches like Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment Therapy (ACT) are well supported by research. They can help you change how you relate to your thoughts and respond differently to uncertainty.
You don't have to solve every possible problem before you move forward. Sometimes the first step is just noticing:
"I'm thinking about this again. Not because I've found a solution, but because I'm looking for certainty."
