Mommy= tired

I am one tired mommy.  I am not at all sleeping well.  I stayed home today with Mac.  He is still not eating terribly much but he is feeling much much better. Enough to be incredibly active.  He drove me up the wall.  Constantly wanted to climb over me and just into everything.  I am exhausted.  It doesn't help that I am a little worried about going back to work tomorrow because I received a TERRIBLE email from the sub I had today........
