Internalizing other peoples problems?

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.

Hi everyone☀️ has anyone ever vented to a friend without knowing it is a compulsion? Meaning like you believe the thoughts so much in your head you vent to them and they agree with you? Which then fuels your obsessions about your relationship even more? I have really done that less lately the more I have learned about my ROCD, but wanted to know if anyone else experiences this? It’s so hard when we think we are just venting and then someone agrees or goes along with the obsession because they don’t understand the OCD..which then fuels my ROCD 😭 idk if I’m making sense lol hopefully someone understands

I posted about this the other day and a therapist responded that if it has the usual ocd tells, then it’s most likely ocd. I’m just wondering if anyone else has experienced this. They say even if it’s new for you chances are others have had the same or similar ocd experience. So, this is new for me and just like when I get an intrusive thought i’ve recently been getting what I call intrusive emotions. I will feel something like sad or jealous in a situation when in reality I don’t feel that way at all. For example, my ocd targets certain family members and if one of them is watching tv and thinks a woman is pretty i’ll suddenly feel sad or jealous when I don’t actually care or feel that way because that’s my family member and I don’t think about or feel for them in any inappropriate way. Also, sometimes when I have a harm intrusive thought my ocd will say that I want something horrible to happen to my family member and I will feel like I actually want it but that’s not what I want or how I feel at all. Is there anyone who has had this or something similar happen?
