False memory surrounding a real event?

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.

Without trying to seek reassurance, I’m wondering if anyone has insight on identifying an intrusive thought vs reality. Something that’s always really helped ground me in moments of false memory ocd is clearly remembering the exact moment the thought arose and how it started as “what if I cheated and don’t remember.” Then the images come and are extremely distressing, but I’ve always found some comfort in coming back to that moment of “this started as what if.” It feels like my brain is almost getting more creative with the thoughts now, and I’ve been having probably the worst anxiety of my life the past couple months after another intrusive thought entered my mind. I woke up after a night drinking and thought to myself “did you kiss your friend and don’t remember?” (Didn’t happen, undeniably proved). The rest of the day I stayed anxious about other things I could have done and poured over all my memories of the night. Then the next day I finally had found some peace based on all the evidence from my friends who were with me that nothing bad happened. I then thought “what about when you went to the bathroom,” which I hadn’t really been thinking about before, and then my mind immediately started flashing with images of me performing sex acts in the bathroom with some person who has no name, face, details, or anything I remember about interacting with them. I think I’m just concerned that this was a moment of genuine memory recall since I hadn’t been thinking about the bathroom before, and it was more of a sudden flash of images and “did you do that” vs “what if you did that.” I’m wondering how others are able to identify that something is an intrusive thought vs reality.

How do you know the difference :( I genuinely cannot keep living in this torment. it all started with an ‘intrusive thought’ where I had like a hazy flash of something reading an article. and I remember thinking ‘what if’ and ‘what is this’ and then that intrusive thought turned into me ‘remembering’ something else. which caused me panic. then I started trying to find evidence because it contradicted what I remembered this entire time. this was last year in like september. fast forward to march this year, it came back up- but this time stronger and with more ‘details’ and what nots. and I’ve been ruminating on it since then trying to remember and connect and It’s like I’ve added all of these details. but are they real? or is this just my OCD? I just feel like if it were real I would have never been able to keep it to myself. but also what if it was so traumatic that I blocked it out? because it all makes NO sense for me to do something like that. but it also fits what I was thinking at the time. idk
