I myself have a very good friend who is struggling with her testimony. She has only been a member for a year and came from a very difficult background. I have struggled with her decisions to back away from the church, but have finally come to realize that she has free agency and I cannot force her to make good decisions. I continue to pray for her, be an example to her, and be her friend. I've turned my focus on trying to change her to changing myself-since I can really only control MY decisions. :) Good luck-I know it's difficult to watch a friend struggle.
