courage and confidence

     Recently ,I really feel tired in body and emotion,and I can't find the reason why I have this feeling. I have totally used up my saving ,even include the money that my families had given me.I am very thirsty for myself,I even didn't buy too expensive  breakfast ,lunch and even didn't eat dinner for becoming thin in the future. However, the price of Shanghai items is too high and my salary is too low to support myself. I am worry about myself and my future. Can I live on my own here? Can I take good care of myself? Can I achieve my goal and my dream? All of which I am not sure, I just want to support myself and realize my dream so that my parents would not be worried about me and my life.
