Prayers coming for both you and Bartie. I can add nothing to what all the others have said except this: whatever happens, Bartie is yours forever and always; the love you give to him has ensured that. Remember: death is not an end at all; it is merely the transition to a beautiful form of life we are not yet permitted to know. When "the day" comes, you will be consumed with grief and pain, but Bartie will pass into a glorious life, perfectly healthy and blissfully happy. Try to think of that. Cry for yourself all you need to, but force a smile, no matter how slight, for Bartie. (The most beautiful smiles are those that must break through tears.) May Bartie's Creator bless you with the faith, the courage, and the strength you will need.
