do you feel there is something wrong with yourself?

I think I expect too much from people then when they dont come through I get upset and angry.

Sure... Everyone will find something wrong in themselves, it's normal, and it's the way it is; nobody's perfect, and who thinks he is, then there, that's their wrong part. I think as long as you are aware of your faults and try to get rid of them by improving your persona, it's okay and it's one of everyone's goals in life.
