Help me please

I went out 2 years ago with some friends and I can’t remember some of the night - we went to a house party and my friends say nothing happened but I’m so afraid that I cheated on my partner and don’t remember it. It’s consuming my every minute and I can’t let it go. I was reading up on false memory ocd the other day and it triggered me into thinking what if something I imagined happening actually happened and I don’t know what to do and I’m scared that because I imagined something a certain way that if it wasn’t the same thing I imagined that it must be true

Hello all, I’ve dealt with various OCD themes and compulsions for pretty much as long as I can remember. In some periods of my life the thoughts and compulsions have been particularly severe, but I’ve also had years where I’m able to keep it under control. This has made me worry I don’t actually have OCD, especially because I haven’t been doing consistent therapy and my therapists have gone back and forth on whether I have OCD. In the past few years, I’ve struggled immensely with false memory ocd, and right now I’m going through probably the most severe episode of my life. I love my boyfriend with all my heart. A few times that I’ve gone out drinking I’ve had the thought before “what if I lost control and cheated tonight” and it’s bothered me severely. Two times before, it’s gotten to the point of convincing myself that because I talked to a man that meant I had cheated on my boyfriend and just couldn’t remember. It has never turned out to be true. About a month ago, I went out with friends and had too much to drink. I was really ashamed of myself the next morning, particularly because I always try to drink cautiously now that I know it can trigger my anxiety. I am ashamed to admit I do not remember the very end of the night getting in my uber and going home. I woke up anxious and extremely worried and immediately started off by worrying if I could have tried to kiss my friend and not remembered. I called him and was immediately reassured nothing had happened, I simply drank too much and went home at the end of the night. I started feeling better, but then remembered a moment I had been in the bathroom. I remembered chatting with people in line about how long the line was, and then being in the bathroom on my phone. I then felt like I remembered people knocking and saying to myself “that wasn’t that long” and leaving. There is nothing concrete that I remember that in any way indicates I cheated, and in fact I have texts with my boyfriend from the whole night telling him I loved him. My friend told me that the only time I was ever apart from him was about 5 minutes and that when he came back I was in the same exact spot he left me in. However, when I remembered being in the bathroom, I thought to myself “what if you cheated on him in the bathroom”/ “oh my god did you cheat on him in the bathroom” and then a series of images of me performing sexual acts popped into my head. I’ve poured over my memory and truly do not remember meeting anyone, talking to anyone, or even finding anyone attractive that night, but the fact that I was drinking makes me worried I’m just forgetting and these images could be real. I’ve been constantly ruminating on these fears for the past month, to the point that the only relief I feel is when I’m able to fall asleep. I’m a law student and it’s becoming extremely difficult to keep up with my classes. I’ve been google searching, asked chat gpt for advice, confessed my fears to my boyfriend, asked for reassurance from pretty much everyone in my life, and even emailed the bar asking for security footage (which I know all sounds insane). I’m a naturally guilty person and feel bad about small things, so I really don’t think I would be capable of cheating and then nonchalantly texting my boyfriend, but these images feel so real that it’s terrifying. I’ve also seen a lot about how I would “just know” and that begins to scare me because then I think “you do just know, you did it” even though I really don’t think I did. I know these posts are not supposed to be for reassurance seeking, I’m just so exhausted and feeling really depressed. I’m wondering if anyone has experienced something similar and has any advice. I’m also wondering if images can feel more real the more you ruminate on them or if it’s a sign of memory. Thank you so much for listening.

This situation just happened and I can definitely remember how it went but my brain is telling me otherwise and I know you guys said to sit with the uncertainty but what if the intrusive thought is so bad like disgusting, I can’t sit with that. Maybe it’s false memory but this just happened. I don’t even know how to live with this
