I can relate to some of what you wrote, but I don't think I'm antisocial, just avoiding certain situations and people. A lesson well and long-learned: people will hurt you if they can, but I've through too much not to still know how to be defensive. I don't know if you are in T but perhaps you could talk through the angry thoughts or inner rage as you describe it. Maybe it's a persistent reaction to something which happened before in your life.
