I was checking Facebook a couple of weeks ago and saw this link to this article that was posted by a sister who had recently returned home from her mission early due to health reasons. I found it insightful and wished I could have handed it out to people when our son returned. I hope it will help people know how to treat these ERM in a loving and accepting way.
