Help me please

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

Can a false memory be based on a real event? Like the false memory is based on something that did happen (there is a time/place/people) but you’re not sure if the action in the memory is real? For example, I’ve been dealing with a false memory and it’s based on the time I went on a vacation with my family and the false memory has a time and place, it doesn’t change and it has a specific action and idk…it just feels like it did happen…especially since it’s based on something that DID happen…idk how to explain it :( I hope it is understandable. Anyways…I hope you guys are having a great day!
