I sympathize with your daughter, but I doubt she is any more lonely or any more horny than any other single Christian woman. Endless millions of women have been alone for many years, either because we never had a chance to marry, or are widowed, or were divorced, or are ill. It’s not exactly a unique situation to be in but I wouldn’t describe it as “hellish.”
This is true, I also have a celibate Christian friend who’s never been married; she wishes she was, but she fills her life with activities, Christian and non, and manages. I guess the “hellish” part is realizing that your same sex attractions in and of themselves are so different and “wrong”, and your chances of ever finding a mate are proscribed by scripture, even if you found someone (as in the case of unmarried women finally finding someone). Also, she’s had many “deliverance” episodes with many pastors, groups and churches. We’re waiting on the Lord, in any case. Thanks for comments and prayers.
