I'm so tired

guesses:

sleeping too long
caffeine withdrawl
not exercising enough
anxiety/depression
sleep apnea
intense computer screen usage before bed (try something like f.lux to change your computer screen color at night)
not enough masturbation/sex before bedtime
iron deficiency

I actually slept well last night :)

I think it could be stress, I have a lot going on and also some conflicting feelings about some stuff that I feel guilty about.

I have been trying to eat better and exersize so hopefully that helps

Thanks for the advice everyone :D

Good diet and exercise is the best way to go.

Also, either get a new hobby and revive and old one. It's a great way to relieve stress and give you something to work towards without getting stress.

Um, cocaine.
