Real event mixed with false memory help

Can it feel like you literally remember a false memory happening? And it feels like the memory has always been there and you vividly remember it happening that way? Because I don’t even know if I’m experiencing a false memory or not but god it feels so fucking real. Like I literally remember it happening. But what’s weird is the original memory was kind of different. 2 years later, the memory is not the same, but it feels like I literally remember it happening. And in this memory, I’m fucking snapping. I’m acting on my thoughts. I feel like a fucking psycho. I hope this is just OCD

I’m reaching out for educational and self-awareness purposes, hoping to better understand something I’ve been mentally struggling with for several years. Around five years ago, I began having a deeply distressing memory involving the fear that I may have acted inappropriately toward my younger sister when I was around 13–14 years old. The details are vague, fragmented, and unclear—but ever since this thought first appeared, I’ve treated it as if it were a real event. I’ve carried immense guilt, fear, and anxiety for years, convinced that I must have done something horrible. Despite asking my sister (who remembers absolutely nothing, has never shown signs of discomfort, and has told me more than once that she would’ve spoken up if anything had happened), the doubt and guilt never went away. The memory feels real, yet there is no external confirmation, no direct recall, and no evidence beyond my own mental images and fear. I’ve also struggled with obsessive thoughts in other areas, such as health anxiety since childhood—frequent doctor visits, checking my pulse, obsessing over illness—and only recently learned about false memory OCD, which aligns with my experience. I’m not currently seeking therapy but would greatly appreciate your professional opinion from an educational perspective: Does this sound more like a real memory, or more likely a false memory created by OCD or anxiety-related mechanisms I am stuck between a normal person or a s*xual abuser

I got pure o. I don't think that's really the correct term but you get what i'm talking about. I would say that i have it because my ocd just picks and chooses what subtype it wants to bother with me today. Right now, i'm suffering with real event ocd and, hopefully, false memories. But i think i might have cracked the code on it. So my real events and false memories are pretty much private related, which makes it worse because there's no evidence or proof. There are some memories (real events) i can think about and accept that they happened. I still feel guilt and shame but i have closure from it. And there's the other memories (hopefully false memories) that i look at and just cannot wrap my head around. They feel so real like they actually happened and it gives me so much stress, but i sit there and think and think and think on it to see if it actually happened. Btw, these false memories come from my real events but in different situations and times. Like if it was true, i would accept it. Whether or not it made me feel guilt or shame, i would still accept it happened. This is what i think i figured out. I can look at a memory and know for certain it happened. I don't need evidence or nothing. The false memories make me question myself if it did happen. It's still very vivid and looks so real like a real memory, but i just can't be for certain if i did that. It makes me feel like i'm in denial of my past. Sometimes they both work together. A real event can happen but false memories can use its work to detail out the event, tryna make it much worse than it was. Or you can be thinking of a false memory but real events can try linking with that false memory to making you think you did do that. If this makes any sense or if what i’m saying is correct or i’m just crazy, please tell me. All advice is welcome. Thank you
