Hey,  have you analysed  the reason , that why  you have  other yet started your career  in spite of your desperateness to leave home. Is it that you are hurting yourself!??.. Have you identified your strengths and weaknesses!??? There  could also be some unresolved issues within you and your family, I think if you can consult a Psychologist and talk it out you might get an answer.

Hi, as I get from what you have described, you and your mother don't have a great relationship. Definitely every child needs love and support from parents, but everyone is not fortunate enough to get it. It's not your fault and not your lone duty to make this relationship work. Kindly work on improving your coping mechanisms, so that you can be positive in life and move ahead without any baggage from your parents. This will decrease your aggression too.
