Why Do I Overthink Everything?

Understanding Your Mindscape Series

By Louisa Steiger MD, MPH

Have you ever found yourself replaying something that happened at work or in a relationship? You turn it over again and again and again, analyzing all aspects of what you said or did and what you could have said or could have done differently, following each thread a little further, trying to arrive at some clearer understanding or a different ending. Maybe you rehash the event so much that you lose track of what is going on around you, or you find yourself lying awake at night, still going over it.

This sort of thing happens frequently to people.

And it has a name: most people would call it overthinking. From a psychological perspective, this is rumination.

Rumination is a defense mechanism. Like all defense mechanisms, its unconscious goal is to reduce a person’s distress. Unfortunately, it’s a maladaptive defense mechanism–it doesn’t actually reduce a person’s distress. Rather, it becomes its own kind of stress, and one that is extremely difficult to overcome.

Rumination is often used by high-functioning, high-achieving individuals. Indeed, it can start as a useful activity for a conscientious person. For a conscientious person, reflecting on a situation, reviewing what happened, and considering how to do things differently next time can be thoughtful, adaptive, even growth-promoting.

But at a certain point, the process shifts.

Instead of leading to clarity, the thinking becomes circular. Instead of arriving at

insight, the mind loops. What began as reflection turns into something more rigid and less voluntary.

Reflection Vs. Overthinking Vs. Rumination

The difference is not always obvious from the inside. Reflection tends to move somewhere. It has a beginning, a middle, and an end. It may be uncomfortable, but it often leads to perspective, resolution, or a decision about what to do next.

Rumination, by contrast, goes over the same ground repeatedly without arriving anywhere new. The questions don’t resolve. The answers don’t feel sufficient. The mind stays pulled back into the same moment, the same perceived mistake, the same self-evaluation.

Over time, this can begin to shape your inner world.

How Rumination Affects the Mindscape

In the language of the Mindscape, rumination narrows things. Attention gets pulled into a single channel. Other perspectives become harder to access. The inner voice often becomes more critical, more certain, less flexible. What might have been one experience among many begins to feel like a defining one. This is part of why rumination is so closely tied to depression and anxiety. It doesn’t just reflect distress—it amplifies and prolongs it.

People often notice:

• Difficulty shifting attention away from certain thoughts

• Increasing self-criticism or second-guessing

• Feeling mentally “stuck” or unable to move on

• Trouble sleeping because the mind won’t settle

  
  

And often, alongside all of this, a recognition that the thinking isn’t helping—paired with the frustrating inability to stop.

Gently Interrupting the Loop

Because rumination is not fully conscious or voluntary, it doesn’t respond well to force or self-criticism. Telling yourself to “just stop thinking about it” rarely works. What can help is creating a small amount of space.

Sometimes that begins with simply noticing: this is rumination. Not a problem to solve immediately, but a pattern the mind has fallen into.

From there, shifting attention—toward the body, toward the present environment, toward something concrete and external—can help loosen the loop, even briefly. Over time, psychotherapy can help make sense of what the rumination is trying to resolve, which is often something deeper: shame, uncertainty, fear of getting it wrong, or a wish to undo something that cannot be undone.

A Final Thought

Rumination is not a personal failing. It is a very human pattern, especially in people who care deeply about doing things well and getting things right.

But more thinking is not always what the mind needs.

Sometimes, what allows the Mindscape to open again is not another pass through the same thoughts, but a gradual return to flexibility—to the ability to hold an experience without becoming stuck inside it.
