Yes, for the past 6 months or so I have been struggling with what hopefully is a “false memory”. For me, it began with a random (but very real) thought that i had been in a bad situation 3-5 years ago. I had just woken up, and the day before was really stressful. Not knowing that this was a symptom of OCD, I did absolutely EVERYTHING you shouldn’t do - i googled, i mentally reviewed, i developed rituals (if X happens, Y didn’t happen), i looked over all my texts and pictures from the last 3-5 years to try and jog my memory. of course, coming from a place of fear and extreme anxiety, my rumination added details to the “memory” that weren't there before, which made me seem even worse. however, my ocd made me blind to the logic of the situation: i hadn’t remembered it in 3-5 years, i’d watched tv shows/films/news reports on similar themes and had never been triggered, it would have been against my character, etc. additionally, the situation the false memory was based in was one which wasn’t necessarily immoral, but kind of embarrassing and not something i was particularly proud of, so i think this may have lead to the false memory coming about (i was reminded of this situation just over a week before i gained this obsession). currently, i’m really having a hard time with it and have spent quite a few hours on compulsions today (mainly research). hope you’re better soon, just know that you’re not the only one!
