I'm having trouble..

first of all, i can't study.
second of all, whenever i study, i fall asleep.

someone PLEASE tell me there's a cure for this.
i get about 7 hours avg sleep a night. thats got to be enough. i eat enough protein. i get enough iron.

i can't focus. i can't even make myself have fun instead, for fear of being swallowed by the guilt--so i sit around on my friday/saturday nights doing nothing. possibly indexing. but usually watching movies. with the roommates that happen to be home.

this can't keep happening. who's got a cure?

please tell me there's a cure.
