I am going through a similar situation, minus having any friends. I used to have friends but now I am literally alone, with a family that lost interest in me and a therapist that lost complete respect. I was once a moral, caring individual but transformed into an extremely angry sociopath in my mid teens.

You're not alone. That saying got old, though, and it certainly does nothing to fix your problems. It does make you feel better, for like 10 minutes tops. Have you tried therapy or medication yet?
