I'm full of hate and i need help? could you tell me what my problem is?Read my details?

I'm 18 btw, I'm good looking ,strong and at first i was into hooligans then i was racist then i begun to meet complete c*nts from my own race so i started to hate them.Then for a while i was trying to give up my hateful views but then they keep coming back when I come across arseholes and I call them every name i can think of to make me feel i've got some backbone.My parents disapprove of my behaviour they do their best to help me out with my issues talk me out out of being racist and violentI and i've seen pschycytrists but i'm struggling to channel it, it's going to ruin my life and probably get me killed. I feel my life is sort of coming to an end even though i'm not dying.Never even had a girlfriend lol.
