Dead Brain

I thought I was getting over the feeling of being unappreciated and betrayed but I think those feelings are here to stay for awhile. I feel "dead" inside and my brain goes into sleep mode when I am not purposefully concentrating on a lesson or a class. Perhaps I need more sleep. Perhaps I need more protein. Perhaps I need a drink. Not really--that would just put me to sleep. Whatever it is that I need, I hope I find it soon and snap out of this funk.
