I, too, know that feeling of overwhelming loneliness, LymaBeane. My situation's a little different in that I live with a man, but he is emotionally unavailable, the relationship is platonic, he hardly says a thing and essentially works, sleeps and watches TV. He's a good man but has no idea how to relate to others. Never married, no kids, career in the crapper, and I isolate terribly due to my depression as well as having given up on friends who betray me.
I often think about that Who song where he sings "I hope I die before I get old"; I'm lonely, virtually broke so retirement won't be an option, feel like I don't have much to offer someone at this stage in the game (58), and worry that the older I get the more health problems will be an issue. It's hell getting old, especially when alone. Parents gone, estranged from brother and sister. Thank God for my dog and laptop!
Prayers for your broken family to be restored and, even if not a special someone, another who will lessen your loneliness.
