false memory

I went to bed one night in November, and I can't quite say what happened, but I believed that I had a "memory" from childhood. I won't discuss what, but I had "remembered" doing something sickeningly awful. This thing came to me almost as clear as a real memory. I remember thinking something along the lines of 'How could I forget doing something like that?' followed by a feeling of complete horror and terror. I have moments of "clarity" where I can't believe that I'm questioning doing this thing, and it appears obvious that it's false. But now, I'm more than often believing that I did. I am spending 24/7 fighting my head, and it's taking me to dark places. I know this is the worst thing to do, but you don't understand, if this is real then I am a monster and I can't just adopt the 'maybe I did, maybe I didn't approach'. I just can't. I have to know. I'm so scared. My entire life is on the line. I don't have anyone to talk to about this. Literally no one. I feel like I'm insane, like I'm a monster, like I'm hiding my true identity from everyone I love. Does this sound like False Memory? Or am I in denial, trying to convince myself this didn't happen? Why does it feel so real? And why do I have moments of clarity? I also had my first nightmare about it last night. Please someone help me.

I’m in an absolutely crippling episode dealing with real event/ false memory. I literally cannot get out of it and it is beyond hell. Can someone please help me with advice? If you have been through this how did you get through?! I’m out of work, the only relief is when I’m sleeping no exaggeration. My husband is being super supportive and Is also taking time off to be with me. Was there a specific medication or any tricks that helped? I’m beyond desperate. Thank you

im going to be vague here, but basically i did something in the past that i regret and it became a huge point of my OCD but i have talked to my therapist and i have mostly moved past it. i watched a video by an OCD youtuber that really put it into perspective. anyway, i have been with minimal worry for a few days, but now im having worries related to i think false memory? basically it’s like “oh but what if i said/ did this and just forgot that means i harmed this person im a bad person”. to me it sounds like textbook OCD but im just wondering if anyone else has experienced false memory / real event at the same time. i have a really horrible memory which is making it even more stressful. any responses are appreciated!
