Thanks everybody. That's kind of what I was thinking...to try and distract myself, so hopefully I can forget over time. It hardly seems real to me anyway. It's like if I found out my parents were aliens

That would be extremely hard to believe, yet you might still sort of believe it cause the proof is in front of your eyes. It's kind of like that. But at the same time, if I try to forget it and pretend I was just a weird kid who drew weird pictures, no big deal, then I think the nightmares will go away and I won't be so concerned. My life has been okay anyway. I do have depression and PTSD, but it's because of another issue. I also got Dissociative amnesia, that was also due to the other incident. Maybe I am just paranoid and working myself up because of all these prior issues.
Sometimes what helps is that I can pretend like it was a movie I watched. With the other thing that gave me PTSD, I try to act like it was in a book I read or movie I watched. That's only when I do get flashbacks and stuff. Mostly, I don't remember what the exact details were.
Thank you to everybody. You're all really kind and understanding
