See that edge..yeah those are my toes hanging over it

Man, I am struggling lately. Between the lack of sleep and the fact the rest of the world doesn't understand that I am on the edge, I am barely making it most days, and certainly not gracefully. I cannot remember the last time I was this tired for this long. I know it will get better, but when you are exhausted all day and can't even look forward to bedtime since you kbow you won't sleep, it is a bit of a bummer. Oh well, off to give an exam tonight and fingers crossed I stay awake while my class takes it!
