Thanks for making this thread. I have the same issue; I have a deep hatred and resentment towards those who have hurt me to such an extreme that I have fascinated about them dying agonizing deaths and me throwing a party over it; I'm that screwed up.

The only thing that helps me cope is focusing on my goals and ambitions. I have dreams of being a successful businessman with the power to change the world and I let that drive me because the thought of being more powerful and important to people than my abusers and everybody who has ever wronged or rejected me makes it all worth it.

Still though, there are some very solid answers here
