Can you...

Call in crazy to work?  I don't know what is wrong with me but I have been feeling really out of sorts lately.  Restless, mostly.  I don't feel like I can stop my brain for spinning at a million miles an hour.  I could probably use a good nights rest or at least a break.  I can't really name one thing in particular that I am spinning on, it's really everything.  I know it's weird and I am having a hard time articulating it.  I do know that I am having a hard time concentrating on anything because there are so many things running through my head, I can't stop on one long enough to do anything productive with it.  Now I'm rambling.  I guess back to work since I don't think you can call in crazy...
