Guessing game

It starts off with thinking you’ve done something wrong but it’s hazy it doesn’t say what but it fits with what you’re afraid of. It then starts adding pictures and scenarios and they start to become more and more detailed until you don’t know what’s real or not anymore. I’ve struggled with this for almost 15 years of the same false memories occasionally adding more details. Has anyone else had this experience of false memories becoming so detailed it’s hard to argue against?

I deal with false memories, I’ve had a few that have been pretty bad, but normally I’ve been able to tell myself “hey, this is false.” I remembered something a few months ago, and a genuinely don’t know if it’s false? When I first remembered it, it never crossed my mind at all that it could be false. I just assumed it was entirely true. But now that I’ve been thinking about it, there is a possibility that it could be false. It supposedly took place last year during the fall or winter, I remembered it last august. It’s an extremely extremely specific scenario, and the memory is kinda complex. I also vaguely remember remembering it earlier, but it now affecting me that much? Although that could have just been having intrusive thoughts related to the subject. With my confusion on whether or not this memory is false of course comes my ocd shoving it’s way into everything. Something my brain has been telling me recently is “if the memory could be false then maybe only parts of it are and you’re actually just a terrible person” (that would make more sense if I explained the memory). And now I have to keep reminding myself that it’s either all true or it’s all fake, because our ocd would not produce the “better part” of the memory without producing the “worse part”.

My false memory is of me assaulting another human and to make it worse it has a real detail being a towel radiator. I tried to guess what I would’ve been leaning on if I was standing in a specific place in a room I went in yearsss ago and I kinda just guessed a towel radiator and to my shock looking back at the old pictures I got it right…I don’t remember assaulting anyone though? It’s scaring me as yes the towel radiator was there but I do not recall harming another human it’s sooo against my nature even drunk. So now my ocd is using that towel radiator against me saying my whole false memory must be real as it has a real detail? I know it’s probably laughable to some people but my whole life is being ruined right now by a radiator. I’ve spoken to a therapist who kept saying she didn’t really understand what it’s got to do with the false memory. My family and partner keep assuring me I would never do that and to just move on. So why can’t I move on?! Anyone dealt with anything remotely similar?
