constantly checking your feelings can really mess you up

OK, this might sound really dumb, but when you guys get intrusive thoughts, do they just come once and then go away? I’ve heard that repeatedly thinking about an intrusive thought is considered ‘checking,’ but it doesn’t feel like I have any control over how many times it comes up in my head. It’s not like I’m trying to check anything—it just keeps showing up, almost like it’s terrorizing me every time. I can’t seem to stop it from looping, stop remembering it, or prevent it from coming up. Every time it does, I feel horrified, and I already know it’s going to horrify me. I don’t think I’m actively trying to see if my feelings have changed, so is this still considered checking? How do other people get an intrusive thought and just move on? Doesn’t it pop up a million times for them too? I always thought that was normal, but now I’m hearing this could be a compulsion, and I feel really confused, scared, and lost. Is this why my OCD feels so extreme? Because I really don’t feel like I can control how many times the thought pops up.

Does anyone else ever feel like they don’t feel “bad enough” to have OCD, or that they don’t feel “the right way” for it? Or like they’re just saying they have OCD as an excuse? Because i was so much better for like 3 weeks now and now im on my period and i started doubting again. So because of that im scared that i was feeling to good and that my fear is actually true.

Does anyone have any advice for how to know the difference between ocd and real feelings/thoughts? Sometimes an intrusive thought will come in and I immediately know it’s ridiculous and I can just leave it alone and it won’t bother me but other times I really really don’t know. It’s when ocd hijacks and twists my real feelings and thoughts and tries to manipulate me into believing they’re something they’re not or something that doesn’t align with my true morals or intentions. But since it’s twisting and mixing with real feelings I get so confused and scared. Everything gets jumbled and I feel like I can’t trust myself or my own mind. Yet other times and other topics I can laugh off and push away just fine. Make it make sense. And then I start to think well maybe I don’t have ocd at all and I’m just in denial because I don’t want to accept that these scary/concerning things are true about myself. Or maybe that’s just the ocd talking.
