OK, you are feeling like you world has fallen apart. I've been there at various times in my life( My Mom suicided; my Dad died suddenly; husband wrongly jailed for almost 5 years). It will get better with time, but you may consider talking to a counselor at school to see if you can see a psychologist. Seeing a psychologist is NOT saying you're crazy, it's saying you need someone to talk this through with and you do! Smoke a few, don't be alone, talk about it.
