Do you ever have those days?

Where you can't really do anything productive or say anything meaningful? Where you just want to watch an "X-files" or "Law and Order: Criminal Intent" marathon and sit? Or what about when you feel down and alone and want someone to call or email you and nobody does? Or when you drive your brother to work and cry on the way home cause of some Pink Floyd song? What about that? Or when you are getting the flu and everything seems to bother you even more?
