Is it normal to dislike most people?

Nothing wrong with your attitude. I have been disappointed by people so many times, that I have no friends. I treat EVERYONE the same and some of them stick more than others according to what they want from me. I just don't give them my all as I used to. i can call them friends or I can call them acquaintances - doesn't really matter. I like them in varying degrees and some I don't like, but they are there.
