Could you possibly get a nanny position? That would get you into your "own" place, make you feel good about helping a family and then maybe you could do school in the evenings? You are young and with that there is usually self-doubt. It WILL get better as you age, trust me. Give it some time. Find something you like to do....maybe drawing, painting, cooking....something to give you that feeling of accomplishment that is really the basis of self-esteem. Big hug!!!
