So you've been to the small group before?
If not, give it a try.
That's what I'm doing this Wednesday, actually.
I'm going to a "normal" church for a change. The kind that houses those kids who are either popular, quiet, or just reeeally nice. With a couple exceptions for the occational obnoxious, annoying kid.
I can't wait to see what happens when I walk in. I already know a few of them though, and they're pretty cool. They could be at your group, too.
I would go to your parents and tell them that a more intimate relationship with God is what you feel is best, and ask if they'd be willing to let you try that for a while instead. If it goes well, they should see that you're fine that way, without what they're trying to force you into.

Worth a shot, and the best I could give right now.
