An unreachable itch

I can't seem to get started to do any work. There's this restlessness in myself. I'm tired ... have been sleeping only about 4 to 5 hours in the past week. Yet, when I tried to take a nap, I can't rest. I'm trying to do work, but I can't give my fullest attention to it. This is just another day where one doesn't feel like oneself. There's this unexplainable, unscratchable itch somewhere.

Arrgh.
