Why Can’t I Stop Overthinking? How to Tell When It’s Become a Problem

Have you ever walked away from a conversation feeling completely fine... until you got to the car? Suddenly your brain starts replaying everything you just said: Did I talk too much? Did I not react the way they were looking for? Should I have worded that differently? What if they took it the wrong way? You put the music on and told yourself to forget about it, but two hours later... Should I text them to make sure they understood what I meant?

We also live in a world that rewards being prepared, productive, and "on our game" all the time. Mistakes can feel bigger than ever. We're expected to excel at work, maintain solid relationships, make countless decisions per day, be aesthetically pleasing, manage the home, take care of our minds and bodies, and somehow make it look effortless... It's no wonder anxious minds think they need to pick apart every detail before they can relax.

It's so common that one of the questions I hear is, "Why can't I stop overthinking?" and the short answer is that you're just trying to protect yourself.

Overthinking is often a hallmark of anxiety, but it's more than just "thinking a lot." And not all overthinking is necessarily unhealthy! Most of us overthink at times, like for an important presentation, a big life decision, or after an awkward interaction. It can be a good thing to reflect on our mistakes or think through our options.

Overthinking alone can be stressful, but it usually leads to something at least somewhat productive: a decision, a lesson learned, or acceptance.

Rumination, on the other hand, is the type of overthinking when you're stuck replaying the same thoughts, conversations, or situations over and over in an attempt to find certainty, reassurance, or the "right" answer. It goes beyond planning, reflection, and problem solving. It may even be so intent that you're unable to focus on other tasks, catastrophizing, or even losing sleep thinking about it. Rumination is actually NOT productive in nature, but instead a hamster wheel that doesn't truly move the needle or resolve anything.

To distinguish, a helpful question to ask yourself is: "Is my overthinking helping me move forward in some way, or am I staying stuck on all the same thoughts?"

When overthinking becomes driven by anxiety, especially in the form of rumination, it often functions as a nervous system strategy: You are scanning the world around you for threats, looking for certainty because your brain believes certainty equals safety; Rumination feels productive because you're trying to predict and avoid pain before it happens. Your nervous system is doing its job by setting off the alarm, but there may not have been a fire to begin with.

To be clear, we're all guilty of overthinking at some point! But if it begins to become a pattern for you across multiple areas of life, or if it's causing more agony and stress to your mental health than it is actually helpful, then you might be getting stuck in this pattern of rumination.

It's also worth mentioning that some of these patterns can overlap with OCD, particularly when the thoughts feel unwanted or intrusive, and when they're followed by a compulsive action. Anxiety and OCD share some similarities, but they aren't the same. A therapist can help you understand which patterns you're experiencing and what treatment approach would be most helpful.

"Why can't I just stop overthinking so much?" Well, you can't stop so easily because you DO actually get some temporary relief: you feel like you are doing everything in your power to prepare, it feels like you're preventing something bad from happening, and it's giving you a sense of control, albeit a false sense because the world is an inherently unpredictable place. If overthinking felt terrible 100% of the time, you probably wouldn't do it, but that's not how anxiety works. Overthinking gives you moments of relief and feeling responsible- and maybe that's why it's so hard to let go.

Despite overthinking's best efforts to prepare, it's counterproductive for the long term: You're actually teaching yourself that you NEED to have this intensity of thought to be effective. Your nervous system's fight or flight response is reinforced every time you go through this process, and the cycle is therefore reinforced. You can't get quality sleep, your stomach always hurts (our brains and guts are very connected!), you're mentally exhausted on a day where nothing memorable happened, and you don't trust your instincts anymore. It feels like you should continue to think about it a little longer to be sure, but unfortunately, anxiety often moves the goalpost without our permission. More questions may arise than answers, and our imagination can run wild with the endless potential outcomes we create.

How To Interrupt The Cycle:

Regulate the body: Your activated nervous system is making your thoughts spiral too quickly; Before trying to think your way out of anxiety, try calming your body first.

-Try moving your attention out of your head and into your body: Take some slow exhales, unclench your jaw, drop and roll back your shoulders, stretch your body, lay on the floor with your legs up on the wall while you do some intentional breathing.

-Engage in vigorous exercise or go walking in nature

-Use the TIPP method when you're overwhelmed (temperature change, intense exercise, paced breathing, progressive muscle relaxation)

Interrupt the thought: Bring your attention outside the loop.

-Name what's happening: "this is anxiety," "this is just a thought"

-Remind yourself, "I know this is my brain trying to keep me safe, but it could be a false alarm"

-Engage instead in a grounding exercise where you bring attention to your 5 senses

Reduced reassurance: This doesn't mean to never ask for support; It means learning to trust yourself before looking outside.

-Delay getting reassurance until you've at least made an initial decision for yourself, so you practice listening to your own voice first

-Practice giving yourself 1 thorough read-through of the email or text, and that's it

Practice uncertainty: The reality is that life is uncertain, so we need to practice tolerating the discomfort of not knowing everything.

-Avoid Googling repeatedly

-Try letting "good enough" be enough

-Schedule a 10 minute brain dump or worry window

-Replace the "it will go wrong" language with "it could go wrong, but if that doesn’t mean I can’t handle it"

If you've spent years trying to out-think your anxiety, I hope you leave with one takeaway: It’s not your fault. Your brain has learned to mistake overthinking for safety. And you can rewire this cycle. Just like your brain learned this pattern, it can learn a different one.

If this felt uncomfortably familiar, know that you don't have to figure it out alone. Learning to respond differently to anxiety is a skill, and it's one that's absolutely possible with the right support. If you're wondering whether therapy might be helpful, here are some signs I would look for to see if it's time to seek support. You can finally understand what's driving your patterns, strengthen your tolerance for uncertainty, and build trust in yourself again.

Take Care,
