I'm sick of life being like THIS!?

They are like that because they aren't happy. They put others down to feel better about themselves. You are bothered by their behavior because you like yourself and don't need to do those things. Start meeting other people who are more like yourself. One suggestion is to venture out to places without the crowd that you are hanging around with now. There is this "Law" in life that says like attracts like. You will meet people that think like yourself, you'll be rid of those less evolved souls that you currently hang around with. (Ooops, I ended a sentence with a preposition. According to your friends, I must be a moron)
