Main part of it is, when I was first diagnosed, I received a blessing by a high priest. In it, I was told to study my scriptures. Since then I have noticed that to be a factor. But for the first month, I was so busy learning to count carbs and exchanges, I didn't study the scriptures. Then when I finally did, the book (which containes Old Testament, New Testament, Book of Mormon, Doctrine and Covenants and Pearl of Great Price) opened to Doctrine and Covenants 42 and my eyes fell upon verse 48: And again, it shall come to pass that he that hath faith in me to be healed, and is not appointed unto death, shall be healed.
Chalk that little experience up however you see fit.
