wait a year and get your ged or something. 3rd grade at 15 confuses me and doesn't seem possible. and definately talk to someone, and keep smoking weed unless it makes you feel depressed, in which case stop. Do whatever will keep you alive and happy for the time being as long as you aren't hurting anybody. But definately talk to someone man, seriously. And not just abuncha potheads, try a shrink. They're good at figuring brains out sometimes.
