Lack of energy and weakness before surgery

I ask for energy and positive guidance for my mother F. May she decide for her health. May the best happen for them.

After almost 50 years of marriage, my mother has been visibly losing energy and zest for life since my father died six months ago. Since she walks with great difficulty due to arthritis, she is to receive a prosthesis on her right knee. The operation has already been postponed once because she is limping along. Now on Tuesday, 16.06. the surgery date. I ask that she has the strength to make the decision that is right for her.
