I hope this most horrible of occurrences isn't what it's suspected to be, and I certainly hope it's treatable 100% percent. May the very healing hands of God almighty Himself rest upon your mother and heal her more then any treatment or any medicine from man ever could, and may they provide you, your mother, and your family with comfort and bless you souls, spirits, and your hearts.
And may the Lord Guide the Doctors hands through the process to healing your mother and may he give them the wisdom and knowledge to do there jobs and figure out what's wrong, and may he provide them whit those thing that are supernatural that they can't cant even understand themselves.
I'll be thinking about you and keeping you in my prayers, and may peace of the Lord be with you.
