That's pretty fucked up and horrible stuff, Kenori.
Obviously, you wouldn't remember it if the abuse stopped when you were a baby, but wow, that can bring out some awful feelings.
I know a lot about child abuse and sexual abuse. As little girls, my mom and her sisters were treated monstrously by a few relatives tied to a cultish society that I'll leave out of this thread. The abuse continued well into their adolescence, but they repressed the memories. My mom didn't start remembering what happened to her until she was about 40 or so, and then it hit her like a nuclear bomb.
Hopefully you won't have to go through those terrible memories, but if you start feeling fucked up, I recommend with all my heart that you consider talking to a counselor for a while.
