My heads really, really messed up?

I can only recommend the herb. Smoke some weed I'm sure if you get caught your parents will realize the urgency of your situation and you won't be in trouble, if you don't get caught then you feel better until you can get the pills. If you can't get a hold of some bud have someone you know who's 18 go into a smoke shop and buy you spice, it's legal weed.
