How do you get over your hatred for someone?

You can resolve things or like talk things out in a way for some answers that you proabably didn't have from them in the past, maybe forgive those people in a way, or if thats not possible focus on the good things and on you and just get out there and relieve yourself from those feelings, maybe also telling yourself that stuff like that happen for a reason and you're stronger and smarter from all of it and come to be glad it happened for that.
