Feeding Tube and Starting Point

I am sick. I have a disease in which there is no cure. Sometimes I think that I may die from this. I have spent many weeks of this summer in the hospital, having test after test ran, all with no answers. Finally, my body gave out, and I had sugery to insert a feeding tube. It is from that I will be getting most of my nourishment for the next I don't know how long. My future looks bleak. No matter how many people pray, I am getting worse.
But, this much I am sure of. No matter how sick I get, I know that God is with me. As I look back at major events from the last 2-3 years, I see that everything was leading up to this moment, this time. Everything that happened has some part in this. It is a total God thing, and I wish that I had trusted Him more. What happens after this, I don't know.
I may die from this, but I know that God is using me and my illness to transform the lives of others.
John 9:3 says " so this has happened so that the works of God might be displayed in his life."
My prayer is that God is using me, to show others Him and His powers.
