Tired... but why?

I feel absolutely wasted today... but I can't figure out why.

Am I coming down with something? - I don't feel like I am... although my neck is rather sore.

On a lighter note - rehearsals start again tomorrow! Yay! It's been too long since the last one.

Snow still covers most of the ground although we have a noticeable thaw now taking place and today it has drizzled on and off with sleet intermingled in with it... quite horrible weather actually... and it's now almost 11 o'clock and the temperature is still 0.8 degrees even though it's been dark for about 6 hours.
