Wnna kill myself cuz my parents?

i havent been able to hang out with my best friend without being watched and questioned for over a month. My mom has grounded me from hanging out with my best frend because i have a b and a c+ (the c+ is a mistake because i was absent and is going back to a b-) They say that my best friend is a bad influence and all and i so sick of it. My best friend i the nicest person in the world, she is a goody two shoes, but she has bad grades. They say that I had good grades ast year cuz i didnt hang around with her. She has nothing to do with it. Eighth Grade is just hard. The c plus is in advancd algebra and the b is in history. My dad thinks im fat and im no longer allowed to eat chips or cookies. I havent eaten breakfast or lunch today. My dad sys that i need to be working out three times a week, when i work out once a week, play soccer twice a week, and go to lacrosse once a week. I cant go on with this anymore am i being ridiculous or are they?
