There are absolutely such things as depression and self-confidence groups. I'd suggest you pop along to your doctors and ask him/her about them, and hopefully they could point you in the right direction for finding such groups. Also - I think it's a positive sign that you're recognising your own feelings and recognising that they need dealt with now. Just because you're a Christian doesn't mean that you should feel happy and have self-confidence or whatever. You should possess those things because it's your given right - we all deserve happiness - and if you don't feel too grand then you should absolutely do all you can to get back to a place where you feel comfortable within yourself. As I said, seeking out such support groups is a really positive thing for you to be doing, and I hope you manage to find some. :]
Other than that, I'm sure you know that there are so many other people out there to help you, yeah? And should you ever need a chat or a rant, or anything at all, feel free to PM me absolutely anytime.
Take care of yourself, and best of luck to you. I really hope it all works out for you.
