supeesh, I am so sorry you feel that way. Tell you what, I have been there. In my own way, of course.
See, What changed things for me is that I started to enjoy what I have. Small things, big things...anything I liked. Do not worry what other people think. Just be nice, friendly ...and SMILE. Lighten up! Life is to be enjoyed, that actually is the purpose of life.
If something is not to your liking, don't dwell on it...find things you DO like.
