Why You Keep Overthinking (and How to Actually Stop)

By Bethany M. Martinez, M.A., APC, NCC

If you’ve ever laid in bed replaying a conversation from earlier that day…

Wondering if you said the wrong thing…

Analyzing someone’s tone…

Or trying to predict every possible outcome before making a decision—you’re not alone.

Overthinking is one of the most common things I see in therapy, especially with adolescents and young adults. And while it can feel frustrating or even exhausting, overthinking isn’t random.

It’s protective.

Your brain is trying to help you.

The Purpose Behind Overthinking

At its core, overthinking is your mind’s attempt to create certainty and control.

If I think about this enough… maybe I won’t make a mistake.

If I replay it enough… maybe I can fix it.

If I prepare for every outcome… maybe I won’t get hurt.

For many people, this pattern develops in environments where mistakes felt costly, emotions felt overwhelming, or things felt unpredictable. Over time, your brain learns:

“Thinking more = staying safe.”

And for a while, that may have worked.

But eventually, overthinking stops being helpful and starts keeping you stuck.

The Problem with Overthinking

Overthinking often gives the illusion of control, but not the outcome we’re actually looking for.

Instead of clarity, it creates:

• Increased anxiety

• Decision paralysis

• Self-doubt

• Emotional exhaustion

The more we try to “figure it all out,” the more disconnected we become from actually living.

So How Do You Stop?

Not by forcing your brain to be quiet.

That usually backfires.

Instead, we focus on changing your relationship with your thoughts.

Here are a few practical shifts I work on with clients:

1. Notice, Don’t Engage

Not every thought deserves your attention.

Instead of:

“Why would I say that? That was so awkward.”

Try:

“I’m noticing I’m overthinking that conversation.”

This creates space between you and your thoughts.

2. Ask: Is This Helpful?

A simple but powerful question:

“Is this thought helping me right now?”

If the answer is no, you don’t have to keep following it.

3. Set Boundaries with Your Mind

This might sound strange, but it works.

Give yourself a “thinking window”—maybe 10–15 minutes to journal or process.

When the thoughts come back later:

“I’ve already thought about this. I’ll come back to it tomorrow if I need to.”

4. Come Back to the Present

Overthinking pulls you into the past or the future.

Grounding brings you back to now.

Try:

• Naming 5 things you can see

• Taking slow, intentional breaths

• Focusing on what’s directly in front of you

5. Take Action (Even Small)

Overthinking thrives in indecision.

Action breaks the cycle.

You don’t need the perfect decision—just the next right step.

Final Thoughts

Overthinking doesn’t mean something is wrong with you.

It means your brain learned to be on high alert.

But you don’t have to stay stuck there.

With practice, you can learn to step back from your thoughts, trust yourself more, and move through life with a little more ease and a lot more confidence.

Because the goal isn’t to control every thought.

It’s to not let your thoughts control you.
