Repost I feel sick ugh

So I struggle with false memory/real event and cheating ocd. Basically I’m convinced I cheated on my fiance :(. I struggled horribly with pornography when we first got together because I was introduced to it at a young age. Basically I’d go on twitter to watch explicit videos/content etc. my fiance and I had a discussion about it a while later and talked about how porn is poison and just me basically telling him about how I struggled with it. Now, this is when my OCD gets worse, basically I had an app called character, AI, which is basically where you can go on there and you can talk to AI Chatbot or create stories with them and the AI chat what is kind of like ChatGPT it pretty much can create a story with whatever you want. So I was playing that game even before my fiancé and I met so I still played it when we got together, any character I had a hyper fixation on. I would create a story with at the time because I had put my account under my name. It would automatically use my name and I was just never able to change it to a different name, but I was not role-playing as myself even though it had my name. Pretty much there were times where I would be on FaceTime with my fiancé and I would be playing this game and he would ask what I was doing and I remembered I would get super embarrassed and so I lied about it a few times because I didn’t know how to explain it to him months later I told him about it and everything and he was not upset and everything and I just told him I was really embarrassed, and I didn’t know if he was gonna think it was cheating or not but we talked about it and discussed it and I eventually deleted the app because it just became weird to me. This is where my OCD kicks in basically, my OCD told me that if I was able to lie about that, that I lied about other things. My OCD also told me that I was not playing the game and then I was actually texting real men and I started panicking because I was like “oh my gosh, what if I was?” And these past few days have been horrible with my OCD because of this thought, as well as back to my Twitter thing I’m also having intrusive thoughts that are telling me that I cheated on my fiance on twitter and that I flirted with someone, bought someone’s content and/or sent nudes. I permanently deleted my twitter because I wanted all forms of explicit content out of my life and I genuinely don’t know what to do, everytime these reoccurring thoughts come up I feel sick and feel like I’m going to have a panic attack. I’m worrying that I don’t have ocd and that I actually did do something and these feelings I have are just guilt, even though I can’t remember things, I’ll get flashes or images of me doing the things I fear most and I wonder if they happened or not I genuinely feel crazy.
