This is extremely sad :/
But I think if I knew that girl, I would want her to go out and make something of herself...I know easier said than done, but see if she can make something positive out of her negative start in life.
Look at David Pelzer, terribly terribly abused as a child. But he put his experiences into a book, and raised awareness of child abuse. He also, had a child and his experiences made him want to be the best father possible. xxx
My verdict is that I'm bloody lucky, that's what. I'm really sorry for what's happened to you OP (assuming it is you), but hopefully things will get a lot better once you're away from your family and can start your own life without them in it. Try and escape OP. Like others have said, what was your education like? Try and run away to Uni!
