Wait, can't you solve your own problems? Anyway, there is nothing wrong with camping...obviously from the other shit you've posted you need something that will get you away from your stupid boyfriend and his stupid friend.
If it's because you don't like camping, maybe consider it if you haven't already, at least for your mom? :]
If it's because you want to spend the holidays doing something else or just don't feel in the mood for it right now, just be honest with your mom, I'm sure she'll understand and be glad you were honest with her. :]
