Fatigue

Was it the camping, or the summation of the last several months of push with home school, and work?  

 I'm home from work on vacation all week and I'm worn out.. I crawl out of bed at 8 am, sluggishly plug along doing chores throughout the day and sink into bed by 10pm.  Even my left leg doesn't want to function at normal speed and positioning. until it's been in motion for a while - explain that!?!

  I keep yawning. Where did my energy go?  

I'm zapped!
