Just another boy

Hi! So I'm just another boy, but I have some issues. I have a little sister which is really annoying, my parents are divorced and very strict, and I also have different personalities. Not like everyone else tho, sometimes it's a different person who controls me and I can't do control it and I don't remember anything from when I become that person. I've heard that I have gotten this "disease" because I've been trough something very rough and needed someone else to keep me alive.

Please don't judge me if I have some bad English, please tell me if I have written anything wrong or to come with improvements. Hope you will enjoy the story
