Without trying to be too judgmental, I get the feeling that you haven't fully made the transition from child to parent yourself. Thus, your situation, while already complicated, is further complicated by the fact that you seem to be reliant on your own parents for financial and emotional support.
All I can suggest is, do your best to become fully self-sufficient as quickly as possible.
