Stuck obsessing over someone and cant turn my brain off

I’m stuck obsessing over someone and I can’t seem to turn my brain off. It’s not even that I want to be thinking about them all day. My mind just keeps replaying conversations, checking for hidden meanings, and making up scenarios that probably aren’t real.

I’ll try to distract myself, but then I notice I’m distracted and somehow that brings the thoughts back. Checking their social media makes it worse, obviously, but not checking can feel uncomfortable too. It’s like my brain is demanding certainty that I can’t actually get.

The hardest part is that the thoughts feel urgent, even when I know they’re excessive. I keep wanting to figure out exactly what they think of me or what every interaction meant. By the end of the day I’m exhausted from arguing with my own mind.

I’m trying to stop feeding the cycle by not checking or seeking reassurance every time the thought pops up. It feels awful at first, but I’m realizing I probably won’t think my way into feeling certain. I may need help with the OCD part specifically, instead of treating every thought like a problem I have to solve.
