Small emotional break down...

My DH is still away at training.  Only 15 days left and I cannot be happier.  This past weekend was insane.  All three of my children had to be in 3 different places at pretty much the same time.  How does this happen?  I am just not sure how to balance it all.  Who is going to suffer in all of this?  I just feel like there is not enough of me to go around and yet I am still not finding any time to be by myself.  Any suggestions would be helpful...is there anyone out there?
