I "came out" when I was 16 or 17. Grew up in a very passionately Christian home. It's the main focus of all of my family, and all their friends and acquaintances are from church or my dad's job (which is in the Christian music industry). My sister went to college focusing on ministry oriented stuff for 4 years, my brother below me is currently interning at a church and my youngest bro is involved in youth group and that's where all his friends are from. It's very awkward in a way but at the same time it's not so hard because I'm in a good family. Though it pains them to know I've turned away, they are no less accepting and loving. It does suck though, a lot because despite things being ok between all of us I do feel alienated. Mostly with my dad he doesn't understand how my mind works. He thinks I've decided it must just not be "convenient" for me to be a Christian but that I MUST believe in God. I don't know that he'll understand that a lot of people just aren't like he is and can't accept things at face value.
I hate the ambiguity of spiritualism and God. It's frustrating.
