Why Can’t I Stop Trying to Figure It Out?
OCD and the Need to Know for Sure

One of the things we hear constantly from people with OCD is some version of, “I just need to figure this out.” Maybe you’re trying to figure out whether you really love your partner, whether that weird thought you had means something about you, whether you could have done something terrible and forgotten about it, or whether you felt the “right” thing in a particular moment. The topic varies enormously, but the experience tends to look pretty similar: you think about it, replay what happened, check your memory, Google, ask somebody else what they think, run through the evidence again, and eventually arrive at an answer that feels reasonably convincing.

Then tomorrow, somehow, you’re thinking about the same damn thing again.

That’s because with OCD, “figuring it out” can become a compulsion. It’s a sneaky one because it looks like thinking, and obviously thinking about things isn’t a problem. The difference is that you’re no longer thinking because there’s a problem that can reasonably be solved; you’re thinking because you need to feel certain before your brain will give you permission to let it go.

Unfortunately, OCD is really good at finding loopholes. You remember another detail that might change things, wonder whether you were completely honest when you asked someone for reassurance, realize your Google search didn’t account for one particular circumstance, or start wondering whether the fact that you’re still worried about it is evidence that maybe there really is something wrong. There is always another angle available when the goal is to eliminate uncertainty completely.

This is why people can spend an astonishing amount of time mentally reviewing something and still feel like they haven’t gotten anywhere. It’s not because you haven’t thought hard enough; you’ve probably thought about it way more than enough. The problem is that OCD keeps promising that if you do just a little more work, eventually you’ll reach the magical point where you know for sure and never have to think about it again.

You probably won’t, because certainty was never actually available in the first place. None of us gets to know with 100% certainty that we’ll never hurt someone, never make the wrong decision, always understand our own feelings, remember everything accurately, or never discover something uncomfortable about ourselves. Most people live with those gaps without paying much attention to them. OCD notices one and says, We should probably deal with that, and suddenly you’re three hours into an investigation nobody asked for.

This is also why reassurance can get messy. Someone you trust tells you that no, they don’t think you’re a terrible person or that yes, your relationship sounds fine, and you feel better. But later you realize you left out a detail. Or maybe they were just being nice. Maybe you didn’t explain it correctly. Maybe you should ask again, but phrase the question a little differently this time. The relief is real; it just doesn’t last very long, which is why reassurance can become part of the same cycle.

ERP treatment for OCD isn’t about helping you finally come up with a good enough answer. In fact, a big part of treatment is learning to stop answering some of these questions at all. You begin noticing when you’re reviewing, checking, Googling, asking, analyzing, or otherwise trying to force yourself into certainty, and you practice allowing the question to remain unresolved instead.

This can feel like absolute shit at first, particularly when your brain is insisting that this particular question is different and actually does need to be solved. With practice, though, the goal isn’t to become someone who loves uncertainty or never feels anxious. It’s to teach your brain that uncertainty can be uncomfortable without being an emergency, and that you can get on with your life without figuring everything out first.
