Is it possible for you to get a memory and think it might have been real and then realize you don't think it happened that way but then get scared that it has to be real because at first it seemed like it was real?

I have had the same false memory/instrusive image of me doing something horrible to someone when I was 12 and they were younger. It is a memory based on a real event. I truly don’t know if it’s real or not but obviously, the more I think about it the more I think it’s true. This has led my mind to become slightly paranoid. I worry that if this horrible image in my head is true then one day the person I might have hurt will come and k*ll me. I’m really scared I feel like I won’t feel better as long as this “memory” is in my head. Does anyone have advice?

can a false memory feel very very very real? because i literally don’t know if something happened or not. absolutely no clue but it feels so real

Idk how to caption it other than that. My whole life I’ve had an issue with memory hoarding and the upside has been that I have a really vivid memories of my childhood and I get to remember my best days, the main downside has always been I have a lot of childhood trauma too and I remember every detail meticulously like I can relive and reanalyze them which has caused issues in my healing. However as much pain as it is to remember bad things so well it’s always been a bit of a comfort bc at least I know for sure even if other people don’t know or don’t believe. But as of lately I I’ve been forgetting things, whether it’s what time I’m supposed to work (and I have compulsions when checking my work schedule bc I’m always scared of reading it wrong so I usually open it up read it close it and open it up again 2-3 times so I usually KNOW) or what day it is, or just small things that I don’t remember saying or doing that other people swear on. I just have always felt like I know at the very least I know and lately I don’t and I’m so scared of going crazy and losing myself like literally my biggest fear. So I hate this. Today is Friday I was convinced yesterday was Friday and I woke up today for my Saturday shift completely convinced today was Saturday. I hate being wrong and making those small mistakes because it’s terrifying to think about what else I’m remembering wrong, or what else do I not “know” that isn’t actually the truth? I’m just so scared of losing myself mind. Has anyone ever experienced anything like this?
