I understand what you are going through...My grandson who just turned 16 last week had to go through chemo at UAB Childrens hospital when he was 3 and 4 years old...I went with them on his treatment days a few times....seeing what he went through and seeing all the other children going through it made me thank the Good Lord for what health he had given me.
You and your family keep the faith and keep your heads up.
Praying the peace we have in Jesus the Great Physician will rule and reign in her precious heart and your family as well and may the doctors, medicine, and procedures be used to heal her. The bible says, "Jesus ever lives to make intercession for us"!!! And may He receive all the glory forever!
