Well, welcome to the forums. The internet is nice for that, I remember being younger and spending a lot of time playing online games with people when I couldn't hang out with others. Especially in given circumstances like that.
Telling strangers your story is a plea for help, hon. How old are you? Has Department of Children and Families stepped in? I'm a foster child myself from a very abusive father and I left him for a wonderful foster family. Now, I'm considered one of my DCF district's biggest success stories. That, and with good grades they pay for ALL your college funding so you don't have to struggle when you finish high school. It's a scary thing to do, but it saved my life.
