Past what ifs

So hard to not engage the thoughts because even though it's from the "past" (i don't even know if im remembering things correctly and it kills me) and i can't change it, I just NEED to prove it to myself that it didn't happen this way. If you'd asked me questions maybe a few months ago, I would have been able to lucidly explain things. Now I just feel like I'm in a constant swarm of thoughts, not knowing if anything is real. If my brain is to be trusted. Wish I could just get hypnosis to forget

im going to be vague here, but basically i did something in the past that i regret and it became a huge point of my OCD but i have talked to my therapist and i have mostly moved past it. i watched a video by an OCD youtuber that really put it into perspective. anyway, i have been with minimal worry for a few days, but now im having worries related to i think false memory? basically it’s like “oh but what if i said/ did this and just forgot that means i harmed this person im a bad person”. to me it sounds like textbook OCD but im just wondering if anyone else has experienced false memory / real event at the same time. i have a really horrible memory which is making it even more stressful. any responses are appreciated!

I look back at all past interactions with others and think “what if they were a minor” even though there is no particular reason to think that they were. Is that a common obsession with Pocd? Has anyone else had this intrusive thought? It’s so scary and exhausting.
