real event ocd

So, I know my capacity to get fixated on things. And it's normally something that's relatively remote but, my latest issue is really getting to me and I was wondering if people have any advice. I'm avoiding getting too into specifics, as I don't want this to get reassurance-y but, in essence.. I came to the realisation recently that people who I'd been "friends" (feels like the wrong term now) when I was younger were not very nice people, and normalized a lot of very unpleasant behaviour towards other members of the group. They really normalized it, sold themselves as figures of authority, as older and more responsible and grown-up than others, and looking back, they acted horribly. And coming to this realisation, that I'd been manipulated into just accepting their behaviour has just... broken me. My OCD has latched onto it and I can't stop feeling irreversibly tainted by it. I've talked to others about it, and they've reassured me, told me it's not a big deal and that I hold myself to too high a standard, but none of that sticks. I feel better for a bit, then think 'Maybe when you told them you were skewing it to make yourself look better' or 'Did you leave out a crucial detail'. I keep ruminating over and over, trying to remember exactly how everything played out, trying to figure out if I fed into the behaviour, if I did something bad myself (because y'know, I feel like I was accepting of it at the time, so what does it say about my own values?). I know I need to stop doing all this if I want to improve, but then some part of me keeps saying 'So, you're just going to let yourself off the hook then?' Normally, I can rationalize my own fears to some degree, assure myself something won't happen, but the realness of the situation, and the fact I only came to understand the reality of it because the thought had been bothering me means it feels so much more all-encompassing. I know confessing in itself is a compulsion, but I keep feeling that if I'm not I'm somehow concealing what I 'really am' from others around me, and any positive interactions are me deceiving them in some way. I feel like I can't enjoy anything in life right now, and a good part of me feels I should not enjoy it ever again. If anybody has any advice on it, I'm all ears. Or even hearing if you relate to these feelings, I might appreciate the solidarity at least.

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!

17f I have a lot of events, but my main and my worst one which is absolutely fucking diabolical was done when I was 14 and repeated when I was 16. Everytime I post something about real event ocd here people are like you are probably didn't do anything that bad, and when they hear what I did they are like yeah that's bad. Someone even asked me if I'm autistic cause "it's crazy how you didn't realize that the thing ypu were doing was wrong at this age." And I kinda agree, like it's fucked up It's just that my event is bad. Doesn't mean I don't have real event ocd. You can have a reocd over the event that was bad, it doesn't mean the event wasn't that bad or you don't have recod. It's just people always expect it to be something innocent and it's not Even a healthy person would feel guilty over it, it's just that I had ocd my whole life and it's making the guilt absolutely destructive, like to the point when I sometimes have a hard time breathing when I think about it, I lost more than a year of life to it, almost checked myself out couple of times if I wasn't so scared of pain/failure, the event haunts me in my dreams, it's in my head 24/7 and I will never able to forgive myself. That ocd. But the event itself was bad. So maybe i deserve it.
