One of my very dearest high school friends came from a nice, big Mormon family. He is a flaming homosexual. He met his boyfriend in church, ironically. He came out, but I assume it was very, very hard for him. He holds on to his faith, though I don't know how people can cling to something that rejects them. I'm not suggesting you're gay; I'm only commiserating on how hard it must be to be the one who is so different amidst your Mormon family.
And buck up, there are more heathens here in good ol' Idaho than you'd think! I grew up with a whole group of the lovlies. :o)
