I wanted to post this video from a fellow MG'er. Her disease is more severe than mine is, but it gives you a good idea of some of what we go through. It's about 9 min long, but I encourage you to watch.
We all can be used no matter what our circumstances are. I have learned compassion through pain, patience through frustration, and surrender through brokenness. God is good. (Be sure to turn off music at the bottom of my blog before viewing video)
