How do I know if it's is ocd

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.

Hey, so I've never actually been diagnosed with OCD. I did a little bit of research, I always thought OCD was organizing things. But I'm not normal, I have this thing where I feel something isn't right. I obsess over it or if I brush my hand over something correctly then it's fixed. Or I have to do this thing on stairs, I'll walk up a few or down them because something isn't right. I read this thing on memories. I know something happened, but then I doubt myself to the point I don't know if it happened. And I think too logically in relationships. I'll put statistics on things and if they might not work out I distance myself, there's other odd things I do. My family always told me I was fine but then said things like I was messed up, and said to just ignore what I felt. Like I was making it up. I don't know what to do, I don't have a doctor currently, I was never diognosed. Is there a way to be sure I have it? Or a way to stop everything? I just want to stop everything, please and thank you. Sorry for the long post. If anyone can help, I would be so thankful.

I was diagnosed with OCD around the age of 6, subtype- contamination primarily. It calmed down as I got older and I assumed it had gone away, but also didn’t realize it can show up in other ways, and it still had been effecting me which I know now. I’m not 31 and I’ve been in therapy for a year and it’s helped a lot, although I sometimes get thoughts that what if some of the stuff I’m dealing with isn’t ocd and I’m exaggerating. I feel like thoughts will feel sticky and I’ll do certain compulsions but then the thought eventually vanishes if I do it a few times which makes me think maybe it’s not OCD since other people/friends I know would probably do the exact same thing. Not sure if I’m making sense, but I guess my question is if that thought comes up with anyone else? Just being unsure if something you’re doing actually is ocd or not.
