Too Much

My mom doesn't realize that I am going through a lot as a 16 year old girl. I lost my best friend at the age of 12 to a terminal illness and then 3 years later lost my another one of my friends to suicide. I'm not like the average teenager, I don't care about sex, drugs and alcohol. I care about acedemics and athletics. I have an A-B average and am in college level courses along with varsity Cheerleading. But all my mom sees is some snarky teenager. The one time I go out and try to relax and enjoy myself she FLIPS and threatens she ship me off to live with my dad in another state. She takes me car, my privileges to leave the house, and threatens to make me break up with my boyfriend. I feel like she doesn't trust me even though I have never done anything to tarnish her trust. She treats me as if I'm out being a ****, sleeping around with guys, and getting stoned 24/7. I'm not, I sit at home, do homework, go to practice, and hang out with my boyfriend like once a freaking week. I want to tell her so much but I don't want to break her heart when I tell her that she is the reason why I cut myself...
