i think something is wrong with me

all i want to do is sleep.

my sleeping pattern is all weird. i've been trying to fix it for 2-3 weeks but to no avail.

i'm really emotional.

i've lost 9 pounds since i got back from college. that's great, but i don't know how i lost the first 7 because i lost them before i started my diet type thing. plus, i don't look like i've lost 9 pounds.

normally i go 25-30 days between periods, and this time i went 38 (i count from the starting day, if that matters). not only is that unusually late for me personally, but it's unusually late in general and that worries me.

anyone know what could be wrong with me?
