sorry to hear your mom broke her hip...hope she recovers quickly.
I can't help with your stress...except to let you know we have been through similar health issues with my wife's mom. It was very stressful but we were able to get through it, not sure how but we did.

edited to add: there once was a time I would of said " we will say a prayer for you and your mom"
I just don't believe that will make a difference anymore. What will be...will be
sorry
