Sometimes it's having trouble falling asleep
Sometimes it's having trouble waking up
Sometimes it's sleeping the entire day
Sometimes it's waking up at ungodly hours
Sometimes it's eating everything in your fridge in one sitting
Sometimes it's not eating anything at all
Sometimes it's blood stains
Sometimes it's bruises
Sometimes it hurts
Sometimes it's numb
Sometimes it's running until you can't breathe
Sometimes it's being motionless for days on end
Sometimes it's the feeling of a blade
Or lukewarm water
Sometimes it's how hard you grip your pen
Or the balled up, crumpled pieces of paper
Sometimes it's watching every move you make in the mirror
Sometimes it's not looking your reflection in the eyes
Sometimes it tastes sweet
Sometimes bitter
Or salty
Or sour
Sometimes it's the cold feeling of the floor against your back
Sometimes it's the soft mattress you lay your head on in slumber
Sometimes it's the day
The afternoon
The night
Sometimes it's the guilt
The wrath
The fright
Sometimes it's clear as can be
Sometimes it's all fogged
Sometimes it's doing everything at once
And sometimes it's doing nothing at all.

There's a word for this.
