Atheist stuck in Christian circles?

Hiya Fluther!
I consider myself an atheist but was raised by concervative Christian parents, whom I still live with. I am attending a private Christian college, which bothers the heck out of me.

Do you folks have suggestions on how to stay sane while I finish my degree, or advice on finding like-minded friends? Please do not suggest moving out because, as much as I would love to make that happen, it is absolutely not a feasible option at this point. (I’m 17.)

Thanks!
