If you've ever said, “I'm so OCD about that” — maybe when noting that you prefer your bedroom to be clean or get bothered when you see a crooked picture frame — I hate to break it to you, but you probably don't have OCD. In fact, you probably don’t even really understand how the disorder works.
And I don't blame you. We only know what we've been shown: TV and movies gave us the frequent hand-washing, the flicking of light switches, and the characters who need every knickknack in its rightful place. But that's not the true face of this disorder.
We all have unwanted thoughts that catch us off guard and make us think, Well that was weird. But if you have clinically diagnosed OCD, your brain says, That thought must mean something terrible about you — let's keep pursuing it. Just had a baby? OCD will hand you thoughts you'd never want to have about your own child. Value being a good person? It'll spend all day convincing you that you're not. Deeply in love with your partner? It'll whisper that maybe you're not.
Real OCD isn't a quirky personality trait. It's terrifying.
The disorder seems to find whatever bothers you and dwells. And you're left scrambling, doing anything to get relief, and solve a problem that was never really there.
Real OCD isn't a quirky personality trait: Having it means you're anxious throughout the day. Your mind feels like the enemy. You might question who you are, what you've done, and even what you're capable of doing. You doubt things most people never think twice about. It's terrifying.
In my 13 years treating OCD, I've seen many patients who had no idea what they were dealing with. “But I can't have OCD, my room is a mess!” they’d say, thinking they understood how this disorder presented.
Here are a few OCD themes that illustrate how it actually functions — and about the treatment that does work.
Common types of OCD themes
False memory OCD
Imagine mentally rewinding your past for hours, trying to figure out if you did something awful that you can't quite remember. Did you hit someone with your car and block it out? Did you say something years ago that ruined someone's life? It doesn't matter if it was 40 years ago or one minute ago. Your memory feels fuzzy.
Most people who have an unclear memory, think, I'm not sure, shrug, and move on with their day. Not someone with False Memory OCD — they have to confirm or negate their fears, because doing so will verify who they are as a person.
So they replay. And replay. And replay. The more they search for clarity, the more convinced they become that something is wrong. That they did something. That they are something. And the memory that was never even real starts to feel like evidence.
Harm OCD
You pick up the kitchen knife to make dinner, and the thought hits: How easy would it be to stab your kid right now? You probably want to do it. Then your brain says, Well, because you thought that, it must mean you're dangerous.
So you start avoiding knives — and also driving, cooking, and being alone with your loved ones, just on the off-chance that you'll harm them.
You tell no one, because how do you say that out loud?
Here's the thing, though: People who actually want to hurt someone don't lie awake disgusted by their own thoughts. The fact that it horrifies you means this is OCD, not who you are. But this logic isn’t enough for OCD, which treats thoughts as facts.
Relationship OCD
You love your partner. But OCD keeps asking: Do you, though? Are you sure?
We naturally analyze any relationship to make sure we're with the right person — that's normal. The difference with OCD is that your brain isn't okay with your partner maybe being the one. Instead, there's anxiety, doubt, and the urge for certainty to know right now.
Relationship OCD has you comparing your relationship to everyone else's. Should I be feeling butterflies every time? Can I handle this flaw forever? You find yourself asking your partner over and over again about a doubt you have. Or googling “how should I feel in a relationship,” then reading responses until there is relief. That reassurance helps for a little while. Then the doubt comes back stronger. Eventually, leaving the relationship seems like the only option to find peace.
Cruelest of all, relationship OCD tends to hit the people who care deeply about their relationships. Because that's how OCD works; it goes after what you value most.
The OCD treatment that actually works
I've listed just three types of OCD — there are dozens of them. But they all work the same way. What do the subtypes I've named have in common?
Uncertainty.
OCD urges you to know something with 100 percent confidence and pushes you relentlessly toward that goal.
The one treatment that works for all of them? Exposure and Response Prevention, which doesn't fight the thoughts or try to prove them wrong. Instead, it teaches your brain that uncertainty is something you can live with. That you can have a terrifying thought and not act on it, not solve it, not get assurance about it, and still be okay.
In practice, this treatment means leaning into the scary thought. Instead of trying to make sense of your anxiety or find an answer to your unending questions, you respond with uncertainty, telling yourself, "Maybe, or maybe not." Those aren't just words. They're the opposite of what OCD wants, which is conviction. "Maybe, maybe not" hands it nothing. When you stop acting like you're in danger, the brain learns and stops throwing out false threats.
It's hard, but it works.
Living your life the way you want to, and risking the same things as everyone else, tends to make any intrusive thoughts more bearable.
And the next time someone says, “I'm so OCD about my shoes,” you'll be able to correct them.
