14 drops.

the blood drips with rhythm.
 4 drops every hour, on the hour.
 the box you keep inside your chest holds all the power. 
you know how to open it, but your hands are weak
 they're shaking and twitching as i pull out my key
 they say when one door closes, another one opens
 but i'm not convinced that i won't be locked in a padded room
 for the rest of my eternity
 you have to make a choice, i have to make a choice
 drop the key on to the floor, feeling weak at the knees.
 swinging and swaying, you fall headfirst through the door.
 the blood drips with rhythm. 10 drops every hour, on the hour.
