Too Quiet when School Starts

My home is eerily quiet.  Both of my children are back at school.  My oldest, to 1st grade and my little one is off to preschool.  I thought it would be so wonderful to have my days back.  I finally get to tackle that HUGE list of to do's.  And don't get me started on the design ideas I've accumulated, then neglected the past 3 months.  I should have energy, ready to take on this adult life without tripping over toys.  So, why do I feel like crawling into bed and watching Yo Gabba Gabba?  Sometimes change is hard, even for those who crave it.
