I don't want to go to juvie hall!!!!?

I've missed too many days of school... and now my parents are going to talk to the principle... I may have missed quite a lot of days.. but I made 2 perfect scores and one very close to perfect on my finals... i never study.. i always sleep in school.. well.. anyways, I may go to juvie.. i have been crying all day.. punching my hand into a wall until it bled.. after my mom told me.. I have been going through some counseling to try and get better with my social problems.. and that has caused me to miss many days.. and i haven't turned in some of the absent notes...and i also went through a stage where i refused to go to school.. because well.. i had some hard times with the people at my school.. I have never committed a crime in my life.. and i never want to or plan to. I am so scared. I have heard it is really rough there... i don't know what to do...
