I have a strong memory of reading a copy of Reader's Digest that had a story about a sick child. It might have been written by the child's mother (or possibly father). I think it was a boy, and he had trouble breathing (he might have had cystic fibrosis?). It was a long story (more than a page or two), and the child died. This would have probably been in the early-mid nineties, but it's possible it was reprinted from an earlier time.
Does anyone else remember this?
