Hey,
Its okay, today I stayed in bed too...I was bummed. I had it all planned to wake up early and go to the gym. It turned out to be a no go. I get depressed at myself when I cannot just start or I do, but it doesn't last really long. It sucks.
I hope you feel better soon. I'm ordering in Pizza, ahaha. So long gym.

Cheers,
