tired.

I am exhausted. I am running on something beyond empty. I have reached the level at which it is actually easier to get only a few hours of sleep because my system has adapted to getting only a little sleep so a full night of sleep becomes more painful than not enough.
This has become my life. I read this column pretty religiously and it usually strikes a chord with me somewhere, but this one pretty much was about me.
How did I get here?
Collectively, the amount of stuff I do should not leave me feeling this way. I am busy, yes, but should I be this thinly stretched?
