Just reading this now, you & your son will be in my prayers. i hope he continues to improve and gets his health fully back soon.
I can sympathize with how helpless you feel being so far away - we're all from OH, and when I was in IL, my sons were in CA...now they're back in OH & I had to move to RI. Frustrating! I think about what I would do if one of them became seriously ill. Thank God prayers know no boundaries!
