Pure O OCD: When Your Thoughts Won’t Leave You Alone

Have you ever had a thought pop into your head that was so upsetting, disturbing, or completely out of character that you couldn’t stop thinking about it? Maybe you questioned why you had the thought in the first place, what it meant about you, or whether having that thought meant something was wrong with you or that you were going to do something really bad.

If this sounds familiar, you may be experiencing something known as Pure O OCD.

Pure O, short for purely obsessional OCD, is a term often used to describe a form of OCD where the compulsions are primarily mental rather than visible to other people. So instead of checking a door lock five times in a row, instead you are replaying a conversation five times.

What Does Pure O OCD Feel Like?

One of the most difficult parts of Pure O OCD is dealing with intrusive thoughts that seem to come out of nowhere. It’s like you could be sitting there watching tv then having a thought about what if you wanted to hurt someone. These thoughts may involve things that go against your values, beliefs, or the kind of person you know yourself to be.
You might worry about hurting someone, question your relationship, experience unwanted sexual or religious thoughts, or become preoccupied with the possibility that you could do something terrible.
The thoughts themselves can feel frightening, especially when you don’t understand why you’re having them.
You may find yourself asking, “Why would I think something like that?” or “What if this actually means something about me?”
The more you try to figure out the thoughts, the harder it can become to move on.

What Are Mental Compulsions?

You might be thinking, “I can’t have OCD. I don’t wash my hands repeatedly, check things over and over, or have any of the compulsions people typically associate with OCD.” But are you sure? What if your compulsions aren’t something you can see? What if they’re happening inside your head, and you’ve been doing them so often that you don’t even recognize them as compulsions?

That’s exactly why Pure O OCD can be so confusing. The compulsions are often mental rather than physical, and they can be just as exhausting and time-consuming. For example, you might repeatedly analyze a thought, replay a memory to make sure you didn’t do something wrong, mentally review conversations, seek reassurance from others, or try to replace an unwanted thought with a positive one. You may also find yourself constantly checking how you feel to determine whether a thought is true or whether you are a good person. These behaviors are often attempts to get certainty and relief from anxiety. Unfortunately, the relief is usually temporary, and the cycle starts all over again.

Is There OCD Therapy for Pure O OCD?

Yes! You don’t have to spend your days fighting with your thoughts or trying to find answers to every uncomfortable question.
Pure O OCD therapy often involves cognitive behavioral therapy (CBT), particularly Exposure and Response Prevention (ERP) and Acceptance and Commitment Therapy (ACT).  ERP helps you gradually face the thoughts, feelings, and uncertainty that trigger anxiety while learning to resist the urge to engage in mental compulsions. ACT helps you to accept possiblities.
The goal isn’t to eliminate every unwanted thought. Everyone experiences thoughts they don’t like. Instead, treatment helps you change your relationship with those thoughts so they no longer have to control your attention, decisions, and daily life.
Learning to tolerate uncertainty and allowing thoughts to come and go without trying to solve them can be an important part of this process.

You Don't Have to Figure It Out Alone

Living with Pure O OCD can feel isolating. You may be embarrassed by your thoughts or afraid to talk about them because you worry someone will judge or misunderstand you. You may feel like talking about it will make the thoughts real.
I want you to know that having an unwanted thought doesn’t automatically mean it reflects who you are or what you want or will do.
If you’re struggling with intrusive thoughts, mental compulsions, or symptoms of Pure O OCD, working with an OCD therapist can help you understand what you’re experiencing and explore treatment options.

My goal is to empower clients while honoring their experiences, strengths, and personal values.
