My mom is a full of herself, paranoid freak.. And she takes it put on me. Help?!?

tell her off. im a year older than you so i understand what you are dealing with at this age. tell her what you want and what you think. and say it sincerely. be like "mom i really appreciate you wanting me to be the best i can be at bball but i really dont want it to be my life i want to be able to be a normal teenager and hang out with my friends and go out." hopefully she will understand.
