Are these obsessions?

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.

So this is not a very major thing at all, but it's something that came up yesterday and I couldn't sleep because of it. I'm a big fan of this video game, it's called Xenoblade Chronicles X. Well, after 10 years, it's finally getting a re-release on modern platforms. It's super exciting. From the clips I've seen, it seems to be a very faithful remaster that improves upon the imperfections of the original. However, what my brain is stressed about is that they sort of changed the user interface/font style of the game in order to make it more legible and less crowded. They also revamped some of the character models too. Not a bad thing at all, but I was such a big fan of the old user interface that all the new changes are stressing me out. It's making me want to purchase old hardware just so I can replay the original instead of the re release So all day I've been looking at side-by-side comparisons and getting disappointed by the new one. Which sucks because there is objectively nothing wrong with it! All of my dreams last night were about the game and I wasn't able to get proper sleep. So is this perfectionism OCD or is this an aftereffect of my other subtypes or am I just being extra nitpicky?

i’m a new user on this app, I downloaded it just cause I was curious, I don’t really know if I have OCD. Because in school all I learned about OCD is things being out of place and having it to be perfect almost like perfectionism, but I’ve just recently realized there’s a whole kind of different types of OCD, some things I struggle with daily is a fear of bad things happening or almost like an impending doom of when is it gonna happen? I’m always in my head thinking feels like I’m having multiple conversations at once. Sometimes it doesn’t even feel like I’m having a conversation with myself. I have horrendous anxiety about everything and anything talking to people being around people. It just feels like it consumes my everyday life and I don’t know what to do. I can’t clearly remember anything from my childhood and some things I feel like I may be imagining I just don’t really feel like a person. I’m always thinking the worst in my relationship over analyzing and stressing out thinking of scenarios or thinking, my boyfriend‘s cheating on me. It almost all feels out of my control.
