Hi Sherie. Just keep an open mind and most importantly remember why you're there. You ain't there for eating too many Mars bars!
It will be easy to find 100 ways in which it ain't for you and that all that all the people there are all crazy God talking religious nuts. Well some maybe but not all. Each to their own and when I stopped making excuses to why it just ain't right for me to be sitting in a church with most people 25+ years older than me on a Friday night and decided that I might just embrace it and put any prejudices aside and remember why I'm there then it started working for me.
All the best. x
