I know what your asking is a very hard request to make. I know I requested the same for my mother, about four years ago. To even type or think this takes great courage and not thinking of ones self. One thing that kept me going was understanding God has a master plan for us all of us and "Greater is he that is in me, than he that is in the world." Thought keeping his praise with good and bad, God gave me a greater understanding of him. I am sorry, you are having to go thought all this, with this you letting your light shine knowing it is hard. One song comes to mind "This little of mine I going to let it shine." I am also going to pray for you, it is very hard to have to go though what you are.
As always I pray for the Five Doves and there request.
