exhausted...

I am exhausted. My body is so fatigued right now that everything is an effort. I feel like I have been hit be a freight train and still standing waiting to fall. I know this is a result of the last two weeks. I swam this morning and it took everything out of me just to show up and then to finish the workout. I struggled to bike 30 minutes tonight as well. I need some zzzzzzz's.
