I really don't think you have any disorder, disease, illness, or whatever. I see someone with some deep unresolved issues.

My GUESS is that the people that bullied you, were people that you once thought highly of. I am also GUESSING that being the victim of bullying, you were unable to defend yourself and now all that anger is coming out.

Just like shezbut suggested, I feel that what would be most beneficial to you would be anger management.

I do wish you the best!!

PS - I have to (for my own piece of mind) say that I am not a professional, nor am I trained in any way. Please understand this is only MY PERSONAL OPINION!

Have a nice day!
Love,
