Seeking help is definitely the way to go as others have pointed out.

If you don’t care about others feeling hurt, well then just think about it rationally: you probably don’t like getting hurt, so you can understand that they don’t either and trying not to hurt others generally makes the world easier for everyone.

Now I would also say that aside of that, you should apologize to people you hurt. Not specifically expecting them to forgive you, but because it also logically makes more sense as it might make them feel less bad about your behaviour.

I would overall try to think about things more rationally than emotionally because it does look like your emotions are your main source of problem right now, and for example thinking that hurting people is going to make them improve is absurd.

And thinking rationally would let you realize what behaviors are not okay, and let you apologize/warn people about it even if you fail to control yourself. While people would still completely be entitled to distancing themselves from you if your behaviour hurts them, it might at least give them some insight that allows them to get less hurt. And once again, less hurt is generally positive.
