Real event/false memory

i feel like i have been posting a lot about this and i will try to stop since now but i just don't know where to start or what to do, and i can't take therapy right now either. my event is about something that did actually happen; i had a boyfriend and we had a 1.5 age difference (i know this sounds stupid) but the thing is that we both started to sext a lot since he was 14 and i was 15. we shared audios videos pictures ect and i don't know how to just let this go, even when i know that i never really forced him into anything and i was always constantly worried about him being comfortable, when to stop and ect. the memories keep coming back to my mind and the guilt is eating me up slowly because i keep thinking that i'm a predator or a groomer or something like that. i don't know how to deal with the what ifs either, lately i haven't stopped thinking what if i sexually harassed or sexually exploited him or something like that. how do i deal with the cycle of guilt and constant what ifs if i also feel like my event is worse than others i've seen? please help me with this. it's getting a lil tiring and even if somedays i know how to deal with this, i still get really triggered sometimes. this wouldn't even bother me before, i wish i could just get back in time before this theme popped into my mind. my life has been a hell since then and i live constantly scared and suicidal.

I know I shouldn’t and I’m trying not to ask for reassurance but how do I deal with this when I made real event mistakes in childhood? I’ve opened up to my cousin about this who’s an adult and believes that kids can be influenced at a young age and mimic things that they see and friends and my therapist. They all see the good in me and my stupid childhood mistakes but the guilt is very strong and even though I’ve opened up It’s telling me to open up more and more and I don’t know what else it wants from me.

(21+ ONLY: TRIGGER WARNING) I have therapy today and I’m nervous. I just started going to therapy and I really like my therapist. She talked to me about doing ERP and I’m really nervous about it. I’m scared to tell her the extent of my OCD, and my themes. I’m scared to tell her about my false memory OCD, because I’m scared that what I did was real and I’m just excusing it as false memory, although I have no memory of it. I’m scared that I am truly a monster and I’m using OCD as an excuse—and that she’ll find out and distance herself. I’m just scared that my whole world is gonna fall apart, all around me.
