I don't hate anyone, not anymore. Hate shows they have an impact on you, and that you think of them, which gives them some sort of importance in your mind, therefore, your LIFE. I let go of that a while a go now.
I used to really hate myself, but I'm working on it, it's not as bad as it used to be. I have days when I think of something I should've, could've done, and that's when I really hate myself. But, I can't change it so there's no point feeding it for long periods of time anymore. I've moved past that (mostly). I just get angry with myself sometimes, and really sad. Like really fucking sad
Holding onto hate is never good. Let's say someone hurt you, badly, and yeah you hate them for a while, but forever? It's hard to let go, I know, but letting go of that actually frees you from it. It prevents you from giving them a second thought, and that allows you to heal better, in my experience anyway.
