Anyone else’s ocd make them think that they’ve been thinking this forever and or there are memories or moments where it makes you think you were thinking it?

I’ve had different themes of ocd throughout my life. Can they all differ such as how the thoughts may present? Currently my thoughts feel so true immediately (like they genuinely feel like what I think) but in the last theme I feel like it may have been more of a “what if I think this” type of situation

Whenever anyone starts to feel like their thoughts are less triggering or they feel a moment of happiness/ relief OCD tells you that you want the thoughts back or you actually like having the thoughts and maybe thats just the person I really am? I feel like im going insane😢

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.
