Don't change.

People hate you? Hmm, why? You still hurt they? Or maybe you hate people? Maybe when someone has hurt you, and it has shaped your character, personality.  And if one day you run out, as they say "shame, why?", Or "serves him right". But what sense is there is a person that only hurts? That it's not your fault. People don't change,  and if you are what you are that people must be respected, or to back off. Apparently they do not understand, do not know about our past. It is sad, but you have no obligation to explain to anyone, unless you want to, but that is an individual thing. You can always try to keep some attention for yourself, despite the bad day stick smile to your face and be nice to others ;) It isn't that easy? Life is not easy.  Remember how in the ass just got from him. All the time you get? People don't understand this?
Wait, they will see.
