I take it Canada's rather secular then? I have similar issues (although in reverse) in the United States, the very mention of not believing in God gets stares. Here's how I cope, I don't mention it. Most of the time it's out of peoples minds and they won't bring it up. If it does come up, take a strong stance. Assert confidently that that is what you believe, don't apologize for it. Adopt a "why should you care, let me believe what I believe, and you believe what you want" attitude towards the whole thing.
I'd also suggest finding a church youth group to join. I go to church (fancy that) just for the community, I'm sure there's got to be at least some churches where you live. Go join up, if not to go every Sunday, than just to get in contact with people who share your beliefs.
As for being forgiven, well you know I can't answer that, but judging by most christian sects, I'd say you are.
