Energy

I am in bed, it's 11:13pm, 6pm, it's 3am, 7:04pm, it's 2pm, it's 12pm, it's 12am, it's 9:45pm.
There is something irregular about this lack of energy, am I doing something wrong here?
I'm too tired to drive, to write, to socialize, to stand. I napped yesterday. I drank a mocha and a coffee today. I'm crashing. I don't have the strength to shower, I don't have the motivation for errands. Tonight I was too sleepy to rent a movie. This is waiting. This is subconscious anticipation, and sore legs, from doing nothing. The thought of exercise exhausts me, the idea of doing something makes my eyes close. I can't hold up a conversation.... I can't hold up my arms.
