I think the first step is acknowledging that you had an awful homelife and you didn't deserve to go through that. I'm sorry for what you had to endure and the psychological scars that remain from it.

I think the next part is trying to cope with life and make good choices for yourself. To start getting rid of people in your life that do more harm than good. I.e. the criminals and pimps that aid you in going down self destructive paths. You should acknowledge that you are a strong person and you made it through hell and back and are still here. You are young and still have a lot ahead of you. I hope you find the strength to make good decisions and get you life going in a positive direction.
