May the good Lord show mercy and kindness onto your family. May He look after your wife as well as the doctors, nurses and staff. May He guide the doctors in their treatment of your wife and give strength to your wife to overcome her situation. May He calm your fears knowing that He is in control. It is with greatest of love that I pray for your wife because it is written in Mark 12:31 - "The second most important command is this: Love your neighbor the same as you love yourself. These two commands are the most important."
God Bless.
