I had a friend who's daughter was the same way. She finally got connected to a really caring and active church and she seems to be doing much better now. Her love now is the Lord and she confesses her celabacy until she finds "Mr. Right". We think it's a miracle!

In the mean time, she could consider adoption. Then she should be encouraged to have her tubes tied. That way at least if she feels it necessary to be with someone, she won't be risking bringing another innocent life into the picture. I feel for you in this situation as it is a hopeless feeling to care about someone and not be able to help them since they obviously can't help themselves.
