sleep and thinking about it

oooohhhh boy.
long nap today. nap breath. probably lack of sleep tonight as a result. i think i've discovered why i love sleep so much. partly because/when i'm tired of course, but mostly i want to sleep when i don't like my current reality. i noticed that the other day - i was pissed off, so i wanted to sleep. another time i was sad so i wanted to sleep. if i get a headache, or an ulcer acts up, or i'm sunburned, or have allergies, i want to sleep.
if i'm happy, i don't want to sleep. in fact, when i'm really happy i can barely imagine wanting to sleep ever again.
i've read that sleeping too much is a symptom of depression, but i'm starting to believe that it's more of a defense mechanism, or even a cure - after i wake up, i feel better. maybe not great, but better than when i went to sleep. it's kind of like a comfort food - when things are really rough i know i'll feel better if i can just have some chocolate, or potatoes, sometimes even a popsicle - something i've had a million times before, that i'm comfortable with, and that can't possibly disappoint me. sleep is like that for the most part (disregarding the occasional bad dream - there is no describing how much bad dreams just plain piss me off for wasting my sleep time).
when i'm pissed off and i can't sleep - that's when things really suck. good thing i have chocolate, just in case.
