Real-Event OCD + Cancel Culture

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.

Being exposed to taboo p*rn as young as first grade ruined my life and now ocd is making me pay for it. I have so much guilt for being a child/teen and looking at taboo stuff, and it was all fictional or anime or whatever but it was still so so gross. and I didn't realize It because I had been used to it at so young 🫠 I think what haunts me most is when I was a kid/young teen (like 12-14ish) and didn't have access to p*rn I'd imagine stuff similar to what I'd seen in the art. I can't even believe I'd imagine scenarios involving kid characters or whatever because it had been so normalized to me and I assumed it was normal since it was fiction. I'm 23 now so it's been a decade since I've done anything like that and I've never had the urge to since but still. I've NEVER been attracted to kids or had any urges or anything ever, even when I was addicted. The thought makes me want to vomit, I'd rather die than associate anything sexual with kids/minors and I think people who groom or assault kids are vile. But I still feel like the fact that I imagined stuff similar to the things I read sometimes when I was young is proof I'm a p*do. I don't think people would believe me if I said I'm not. I just feel like I don't deserve to live or that if I do, I'm living a lie. I know 'I was a kid too' but even when I was 13/14 I read/imagined stuff with characters younger than me because I thought it was normal. I'm so disgusted. I've had this theme for so long I'm starting to wonder if ocd is right. I feel too ashamed to tell my therapist.

What ERP or other techniques do you use to combat fear of cancelation? Especially curious about those with taboo thoughts, false memory ocd and event ocd based off of real events where the fear of cancellation may actually hold some validity. I once did my own ERP not under a therapist but just on my own I decided to create an anonymous account on Twitter and defend a friend who was receiving online criticism. I knew that this would be semi-controversial so I was expecting backlash and when I recieved troll replies it actually seemed to be a really helpful low-stakes exposure activity. Is this something that others have done? Low stakes online posts etc. that you know will recieve negative responses? I have had severe OCD as a kid as pretty much every subtype under the sun, and as an adult I pretty much have all the types under control except for this real event and false memory and taboo thought OCD. It seems like a different beast since it's somewhat realistic in the camcellation culture today, and it's confusing to address. Ive shut down almost all social accounts and it's keeping me from progressing in a career where I need to have an online presence :/
