mrsH,
I know you are upset...your house is your home and it is the only home you have known for quite awhile. yes, it is a loss but your new home will be ready for new memories that you make with the kids.
The market is awful right now so hopefully it will not sell for awhile.
JA has not lived in your house for more than two years so this is not affecting him like it is you...ignore his "excitement", all he is seeing is $$.
How is school going? You must be so busy studying and being a mom!! I know how that is!
Hope all is well.
