Back to school blues

In spite of the fact that my children are in their third week of school, I have the "back to school blues" and am fighting tears.  Our old school district begins today, and my sadness isn't for my kids, it is selfishly for me.  My kids love their schools here, and I'm very glad they are here.  I am so very sad about all of the people at the old school that I'm going to miss.  I very much miss the teachers who had become my friends, and I very, very much miss all of those awesome kids!    I guess it's kind of like a reality check.  Life there is going on without us (well, yeah!) and I just feel a little lost.  I told Andrew from the beginning that while I had no doubts this was the best move for our family, for me personally it meant giving up a great deal.  And I was okay with it because I know with certainty this was a move our family needed to make...but today I'm just a little sad about what I left behind.
