Oh Andy!
I am so sorry!!! Stress is a horrible thing for all of us but it is especially bad in MSers. Please do everything you can to take good care of yourself. I know that most of this is unavoidable. It is not like you asked for any of this but do be careful! Please be willing to ask for help. Get anyone that you can trust to take some of this off of you. You need help with the move. You may need help with the kids, cooking, cleaning etc.
If you haven't already, please check into getting and good counselor. You are going to need someone to talk you through this!! I am thinking of you. Take care and thank you so much for letting us know.
