I love my faith, it helps me hold together when life feels overwhelming, and I know exactly what you mean about Greenbelt, I went a few years ago but it was not for me, although in my late teens (as I was at the time) I got more out of it than I would now, mostly I remember the friends I went with and the overly bigness of everything and wishing things were smaller and therefore more interactive and intimate.

You have friends who love you, don't worry too much about faith, its mostly about what you believe about yourself and how you life your life. My mum always says that everyone sees the same God through different windows of the same house (think playschool), mostly I think we all see with different eyes and not everyone is willing to look, but there you go, I never said I was sane.
