Just close your eyes, tap your heels and think, "there is not place like home, there is no place like home"
JK!
Girl! if you have lemons...make lemonade!!! you don't necessarly have to be with your in law family all day, do you? go visit places you haven't viit while there. eat out and think that your babies are doing well and in a few days everything is going back to normal.
Good luck!
