concentration not happening

I thought that I was ready to go back to work for a second day, but I could barely stay awake last night. Maybe staying awake all day Monday took more out of me than I thought. It wasn't as though I didn't try to get some sleep on Tuesday and Wednesday, but I just wasn't me. Then as much as I like class I was completely exhausted by the afternoon and couldn't wait to get home. Concentration was at an all time low.
