Dude, you need to get your self to school as much as possible. I regret not going to school all the time. Belive me it does catch up with you when you leave and you cant get a decent job and the money sucks.. Yes you could turn to selling drugs but that would be pointless when you can do something about it now while you can.. Your also causing your mom alot of shit that she probley dosent need.. You are the ONLY ONE who can sort this out.. so do it man...

GOOD LUCK
