Usually, I play Radiohead's "The Bends" or Neutral Milk Hotel's "In the Aeroplane Over the Sea" when I get in a mood like this. Helps me either focus my energy or get some sleep. Sadly, I left the former at work and let someone borrow the latter. We'll have to try something else tonight.
I'd like to say I'm going to bed now...but I wouldn't be surprised to see another post from me sometime in the wee hours of the morning.
Body and mind must resign together, and in the summer, they lose track of each other quite easily.
