My prayers are with both you and your mom for strength and healing.
So sorry you have to go threw this! We are all praying for you and your family! I can tell you God works in mysterious ways! So keep in mind if mom is still in a coma she is sleeping so her body can heal itself to it's best potential and she is not in pain at the moment. Keep telling her how you love and miss her! I hope all your prayers get answered and mom recovers soon.
Huggs and smooches,
