Reuven,
Prayers for your whole family and a misheberach for your wife Yaffa bat Sarah. (you did not make a typo in your earlier post, when making a misheberach the mother's name is used.)
I hope your rabbi and congregation are helping you and your family. Perhaps they are making arrangements with people closer to you geographically.
Don't neglect your own health at this time, you need all your strength to take care of your wife.
Let those around you help you (it's a mitzvah) they truly care about you. Let them help you and everything will work out ok.
