Sometimes you wonder why you ever bothered. Your daughter has my sympathy. Where were the elders when she was laid up, wouldn't it have been better for the elders to ask people to bring their studies to your daughter's house so she could get time in whilst convalescing. They could also have arranged for her to go on RVs so she wouldn't have to risk further damage. They could also have taken her off for two months. The fact that they did nothing to support her shows they failed her.
Their insensitive handling of the issue shows their lack of support rather than your daughter's lack of committment. To give such a talk was totally reprehensible and shows that there is no love. However it is true Cults shoot their wounded.
