False Memory OCD and actual memories

Any advice? I just got triggered by false memory OCD. There is no indicator or memory of me doing anything bad, only the what if. So how can I deal with uncertainty because if I did do the false memory it would go against my morals?? Not something extremely unforgivable just like not ideal and against my morals… I don’t know if it happened. I have no memory of my false memory happen only the “what if” which is enough to scare me FOR CONTEXT: I was in the mental hospital when I was 16, and made a few friends. Some just a grade below me, so 14-15. I remember bringing up in convo someone I met previously at the mental hospital earlier in that year a different time I was hospitalized , to which a boy responded he knew her, and they did (seggsual) stuff at their school. The girl I was talking about at that time was 14. So im assuming the boy was 14 as well. 13 and up is together in the hospital, so he couldn’t be younger than 13. I have no memories of him flirting with me or me flirting with him. Or anything bad happening. Literally just “what if”.. or what if he wasn’t 14 but 13 and u said something inappropriate or flirted with him. I will never be able to know what happened and I’m sick thinking about this. 13 and 16 is NOT WITHIN MY MORALS. I am worried because the only inappropriate I guess convo had is when he was telling me what happened between him and that girl I knew. I also remember him having a bulge down there and it freaked me out and made me feel weird at the time because I noticed it. (At this time I was already diagnosed with OCD and experienced POCD) I try to tell myself maybe maybe not. But the what if it did happen makes me feel like a p33do, and me thinking it didn’t happen doesn’t satisfy me because I don’t have 100 percent certainty

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!
