Have you ever had a thought that should have taken five minutes to think through, but somehow stayed with you for hours? Maybe you sent a text and then reread it several times, wondering whether your tone sounded wrong. Maybe you had a conversation with someone you care about and found yourself replaying it later that night, searching for something you might have said differently. Maybe you are facing a decision and keep going back and forth, imagining every possible outcome and wondering which choice will lead to the least regret.
And sometimes, it is not even one big thing. It is everything.
Your mind moves from one question to another. What if I made the wrong choice? What if they are upset with me? What if something goes wrong? What if I should have handled that differently? What if I am missing something?
Eventually, thinking can start to feel less like something you are doing and more like something that is happening to you.
As a therapist, I hear this experience often. People sometimes come into therapy feeling frustrated with themselves because they cannot seem to “just let things go.” They may tell me, “I know I am overthinking, but I can’t stop,” or “I wish I could just turn my brain off.” There can be a lot of shame underneath those words, as though having a busy mind means they are doing something wrong.
If this sounds familiar, I want you to know that overthinking is not a character flaw. It does not mean you are weak, difficult, overly sensitive, or incapable of making decisions. Often, overthinking develops because your mind is trying very hard to protect you.
When Thinking Becomes a Way of Trying to Feel Safe
There is an important difference between thinking something through and getting caught in a thinking loop. Thinking can help us understand a situation, solve a problem, make a decision, or learn from an experience. But sometimes the thinking stops moving us toward an answer and starts circling around the same uncertainty. Being stuck in worry and rumination (which are forms of repetitive negative thinking), can be exhausting.
From the outside, it can look like you are simply thinking too much. But when I sit with someone experiencing this in therapy, I often hear something much more understandable underneath it: “I just want to know that everything is going to be okay.”
That is a very human desire.
We want to know that we will make the right decision. We want to know that someone is not angry with us. We want to know that the relationship will work out, that we will not fail, that we will not disappoint someone, that we will not make a mistake we cannot undo.
The difficulty is that life cannot give us that level of certainty. So the mind keeps trying.
Maybe if I think about it one more time, I will finally feel sure.
Maybe if I replay that conversation, I will figure out exactly what they meant.
Maybe if I imagine every possible outcome, I can prevent something bad from happening.
Maybe if I make the perfect decision, I will not have to experience regret.
This is one of the reasons overthinking can be so exhausting. The goal is often not actually to think. The goal is to finally feel certain enough to relax. And when certainty never arrives, the thinking continues.
The Problem Isn’t That You Think Deeply
I want to make space for something here because I think it gets missed when we talk about overthinking.
Being thoughtful is not a problem.
Being reflective is not a problem.
Caring deeply is not a problem.
Wanting to make a good decision is not a problem.
In fact, many people who struggle with overthinking are incredibly conscientious. They care about how their actions affect other people. They want to do things well. They think carefully about their relationships. They notice details. They may be highly responsible and deeply self-aware.
The difficulty begins when thinking becomes the only way you feel able to cope with uncertainty. You might notice yourself looking for reassurance before trusting your own decision. You might repeatedly ask other people what they think, only to find that their reassurance helps for a little while before the doubt returns. You might research something endlessly because making a decision without knowing everything feels uncomfortable. Or you might replay something from the past because part of you believes that if you analyze it enough, you will finally understand what happened.
These behaviours make sense when we understand what they are trying to accomplish.
They are attempts to create certainty, when certainty is not always available. And sometimes the more we chase it, the less settled we feel.
Why Your Brain Keeps Going Back to the Same Thought
One of the most difficult things about overthinking is that it can feel incredibly convincing. When you are inside the thought loop, the next thought feels important. It feels as though you need to figure something out before you can move on.
But repetitive thinking does not necessarily mean that the thought is important. Sometimes it simply means your mind has learned that continuing to think is a way of responding to discomfort. For example, imagine you are waiting for someone to respond to a message.
At first, you may notice a small thought: “I wonder why they haven’t answered.”
Then another thought appears: “Maybe they’re upset with me.”
Then: “Did I say something wrong?”
Then you reread the conversation.
Then you remember something from a previous conversation.
Then you imagine what they might be thinking.
Before long, you are no longer responding to what you actually know. You are responding to a growing collection of possibilities.
This is where anxiety and overthinking can become closely connected. The mind is trying to resolve uncertainty, but because there is no new information available, it keeps generating more questions. And more questions do not always create more clarity, sometimes they simply create more questions.
What I Often Want Clients to Know About Overthinking
One of the first things I want people to understand in therapy is that the goal is not to have a completely quiet mind.
You will still have thoughts.
You will still worry sometimes.
You will still replay a conversation occasionally.
You will still have moments when you are uncertain about what to do.
That is part of being human. The goal is to develop a different relationship with your thoughts so that you do not have to treat every thought as a problem that needs to be solved. There is a subtle but meaningful difference between saying, “I need to figure this out,” and saying, “I am noticing that my mind is looking for certainty right now.”
The first puts you back into the problem. The second gives you a little space from it. That space is often where change begins.
Learning to Notice When Thinking Has Become a Loop
A simple place to start is to notice what your thinking is actually doing.
Ask yourself: Am I moving toward a solution, or am I going around the same question?
If you are problem-solving, there is usually something you can do next. You may need to gather information, make a decision, have a conversation, or take a practical step. If you are overthinking, you may notice that you have already considered the same possibilities several times. You may be asking questions that cannot currently be answered. You may be trying to achieve a feeling of complete certainty before allowing yourself to move forward.
This distinction can be surprisingly helpful. You do not have to argue with the thought. You do not have to force yourself to think positively. You can simply recognize, “I have thought about this before. I am looking for certainty that I may not be able to get right now.”
That is a very different response from getting pulled into another hour of analysis.
What if I Make the Wrong Decision?
For some people, overthinking is especially noticeable around decisions. Should I stay in this job? Should I send the message? Should I say yes? Should I say no? Did I choose the right relationship? Am I making the right move?
Sometimes the decision itself is not the hardest part. It is the possibility of regretting it.
When we believe there is one perfect choice and that making the wrong choice could have lasting consequences, even small decisions can begin to feel enormous. We may keep gathering information, asking for opinions, imagining different futures, and waiting for the moment when we finally feel completely confident.
But confidence does not always arrive before action. Sometimes confidence develops because we learn that we can handle the outcome of our decisions, even when those decisions are imperfect.
This is something I often explore with clients: “What if the goal isn’t to know that you are making the perfect decision? What if the goal is to trust that you can support yourself through whatever happens next?”
That shift can feel uncomfortable at first. It can also be incredibly freeing.
Learning to Live With Some Uncertainty
One of the deeper pieces of overthinking is learning that uncertainty is not necessarily a sign that something is wrong. Sometimes uncertainty simply means you do not know yet.
You cannot know exactly how another person feels.
You cannot know every possible outcome.
You cannot guarantee that a decision will turn out exactly as you hoped.
You cannot go back and change every moment that you wish you had handled differently.
And that can be incredibly uncomfortable. But the answer is not always to think harder. Sometimes the work is learning that you can feel uncertain and still be okay.
You can make a thoughtful decision without knowing everything.
You can have a difficult conversation without knowing exactly how the other person will respond.
You can make a mistake and repair it.
You can disappoint someone and still be a good person.
You can experience regret without needing to punish yourself for it.
You can care deeply without taking responsibility for everything.
These are not overnight changes. They are skills we develop gradually, often through practice and with support.
A Gentler Way to Respond When Your Mind Starts Spinning
When you notice yourself getting caught in an overthinking loop, try starting with curiosity rather than criticism. Instead of, “Why am I doing this again?” you might try, “Something feels uncertain right now, and my mind is trying really hard to make me feel safe.” Then ask yourself, “Is there something I actually need to do?” If there is, identify the smallest next step you can take. If there is not, see whether you can allow the uncertainty to exist without continuing to analyze it. You might take a few slow breaths, notice your surroundings, step outside, write down what is on your mind, or return your attention to whatever you were doing before the thought took over.
The point is not to distract yourself from every uncomfortable thought. It is to practise choosing where your attention goes rather than automatically following every thought your mind produces.
While practicing this, please be gentle with yourself. Self-compassion is not about telling yourself that everything is fine when it isn’t. It is about responding to yourself with the same understanding you might offer someone you care about. Sometimes the most helpful thing you can say to yourself is simply, “I am having a hard time with uncertainty right now. I don’t need to solve my entire life tonight.”
When Overthinking Starts Taking Up Too Much of Your Life
There is nothing unusual about occasionally getting stuck in your thoughts. Most of us do it. It may be worth seeking additional support when overthinking begins to interfere with your sleep, relationships, work, concentration, decision-making, or ability to enjoy your life. You might feel mentally exhausted even when you have not done much physically. You may find yourself constantly seeking reassurance, avoiding decisions, replaying conversations, or worrying about things that have not happened.
You may also notice that your mind becomes particularly busy during periods of stress, change, conflict, or uncertainty. You do not need to wait until things feel unbearable before reaching out for help. Therapy can be a place where you do not have to figure everything out by yourself.
You Don’t Have to Figure Everything Out Before You Move Forward
If you are someone who overthinks, you may have spent a lot of time believing that the answer is somewhere inside your thoughts.
Maybe if you analyze the situation one more time, you will finally feel certain.
Maybe if you understand exactly why something happened, you will finally be able to let it go.
Maybe if you anticipate every possible outcome, you can protect yourself from being hurt.
But sometimes the way forward is not found by thinking more. Sometimes it is found by learning that you can tolerate not knowing.
You can make a decision without having every answer.
You can trust yourself even when you feel uncertain.
You can make mistakes and recover from them.
You can let a conversation be imperfect.
You can stop asking your mind to guarantee that everything will be okay.
You can learn that you do not have to earn the right to rest by figuring everything out first.
If your mind feels like it is constantly running, you are not alone. Overthinking is something we can work with, understand, and change. Therapy can offer you a space to slow things down, understand what your mind is trying to protect you from, and begin developing a more trusting and compassionate relationship with yourself. You do not have to have everything figured out before reaching out. Sometimes reaching out is the first step toward not having to carry it all alone.
If this resonates with you.
If you find yourself constantly replaying conversations, second-guessing decisions, worrying about what might happen, or feeling exhausted from trying to think your way into certainty, you don’t have to keep carrying that mental weight on your own. Overthinking is often connected to something deeper, whether that is anxiety, self-doubt, perfectionism, fear of making mistakes, or difficulty trusting yourself. Therapy can offer a supportive space to slow things down, understand where these patterns come from, and begin developing a different relationship with your thoughts and uncertainty.
