Can I say how that I'm being hateful and can't make myself do anything otherwise to fix it?
why do you have to be hateful?
I enjoy being upset and therefore upset other people around me.
By being hurtful you're hurting yourself. It's not good to hate people for no reason.
I don't need to stop being hateful and I don't care what people think about it.
Well, you can get therapy, which is a good way to stop being so hateful. You need your life to be positive and to uplift others instead of bringing them down.
