I was raised as a 'Christian', which to me meant believing in God and being a good person. But at 14 i got saved. My friendships came and went, so it wasn't an issue for me. And i was never popular, so that wasn't affected. But going through high school as a Christian metal head didn't help me fit in any. Wearing Christian t-shirts to school, carrying a bible. Then going to church with long hair. So i get the point about being the 'bible thumper'. But, i embraced it. That's why i wore the shirts and carried a bible. I was 'that guy that carries a bible'. And i didn't care if people didn't like it.
Do to my boldness i actually got a lot of respect for being the only person (yes, only) in my high school to be a Christian, and standing up for it. I'm sure i got trashed a lot too. Fortunately not a lot of it to my face. But still, it was who i was and people had the choice to accept me that way, or move on. And if they couldn't accept and respect it i didn't bother with them.
As far as the single aspect, well, that was mostly my own issues. Focusing more on being single and how 'horrible' it was rather than just focusing on more productive areas of my life. I find with most Christian singles, they are their own worst enemies.
