Kathy,
I under what you are saying about you situation of blindness and wanting 
sight.  In 1970, while I was pastoring the Cleveland Avenue Christian CHurch 
in southeast Atlanta, I had a cornea transplant. I had been praying for some 
time asking the Lord to give me sight that I might serve Him better. There 
were many other Christians in many states that were praying with me.  I was, 
at that time, a member of a christian network on Amateur radio and met with 
many preachers and other christians each morning on the radio. The time 
came, I received the call and rushed to the hospital.  They had acquired a 
cornea and were ready to do the surgery.  I p[rayed so hard for sight but I 
told the Lord that I realized that I didn't know the future and I knew He 
did.  I told Him that if I could be a better servant without sight then 
please don't give it to me. Everything went extremely well and I was, after 
the surgery, able to see far more light and color than before and to see it 
from a much greater distance.  Later, maybe more than a year later, while 
lifting weights with a friend of mine three times a week, I hemorhaged in 
the left eye and subsequently lost all my potential vision.  I was told by 
my doctor that when the eye hemorhaged, it started to degenerate and the 
optic nerve had died. So, I took it that I could serve Him better without 
sight.  I know of many times when people have been blessed by people with 
handicapps or disabilities.  I remember, too, that the apostle Paul said 
that God told him when he ask for the removal of his "thorn in the flesh" 
"My strength is made known in your weakness.  I believe that people see 
those who have some limitation or disability gladly serving God and giving 
Him the glory for all they are and have and they are encouraged.
God can certainly use you and any of us with our blindness to be a real 
blessing and encouragement to many.
