Getting sick of this

I've gotten diagnosed with OCD and I'm in therapy. But I'm worried that I don't have OCD/that I got misdiagnosed. And recently I'm worried that I've just gotten myself into a habit of thinking of dirty minded or just plain old terrible things after I see/hear certain things because I feel like I need to prove I have OCD or else I'm faking(sometimes this goes away). Or that I'm just mimicking symptoms of ocd to cope with real problems I may have and that im just really deep into denial. I don't know...I'm just so tired. I mean, what if I really am what I think I am and this is my brains only way of coping? I don't even really feel anything towards most of the thoughts anymore either I just know they go against my values and I don't want them. I don't know if that's because I'm so mentally exhausted, I just don't care, or that the thoughts are true and I'm comfortable with them.

back in october i made my first post about my specific type of ocd, how it mixes in with my day to day and how i “deal” with it. i talked about the starting point, how it gradually got worse, and then how it was going just a few months ago. i always think it’s insane how much can change in just the course of a small to a large amount of time. right now, i honestly feel like garbage. to be quite sincere i really want to give up, i’m barely holding on by a thread. and if i cut that thread, i really doubt anyone would care. i’ve never considered myself to be a suicidal person, and i still don’t consider myself that right now. it just gets to a point where it’s just, a lot to deal with. i don’t really enjoy things a lot nowadays. sure i have good days like everyone does, like today, when i was just enjoying my day without worries. but then it all comes crawling back twice as bad the following days. i take online college so i’m usually just stuck at home most of the time. but, when i do decide to actually go out and leave my house, my ocd just explodes because i have this whole routine i need to do or else i feel like i’ll contaminate wherever i end up going. i’m not going to go really deep into my compulsions because it’s hard enough to live with them, much more having to type them all out in detail. but when i go out my compulsions go from wiping down all my stuff i’m going to use after showering, to washing my clothes/cleaning the washer + dryer. i also have separate things (or two of the same thing) i use specifically in my house, and items i use when going out. such as shampoo/body wash, deodorant, lotion, hair curler, etc. as if that’s not draining enough, i also feel the need to fast a couple days prior to any plan i make because i’ve forced myself to believe i need to feel empty in order to be clean. i’m not sure if that’s my past eating disorder talking, or my ocd, but my brain can’t help but think any food in my house is utterly and completely contaminated. i’m so tired of this feeling, feeling like nothing will ever be clean again. feeling like my ocd is trapped in my childhood home. feeling that wave of diseases rushing through my veins the moment i step foot into what’s supposed to be “home”. and i’m so scared of therapy because what if i do get healed, and then everything comes rushing back the second i step into my room. i’m planning on moving somewhere far from my current house in this next coming year, so sometimes i feel like just waiting it out. but it’s insufferable when going to hangout with someone. i miss my friends, my family, and my partner. it’s crazy to me that i’m dealing with all this at the young age of 18 but, i’m sure lots of people have it way worse. i just want to find a way out, any possible way. but i keep pushing myself deeper and deeper that when i finally find a way, it will no longer exist.

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.
