당신 can go on the 조언 spot for this if 당신 want; I would be glad to help 당신 out.
I'll just skip to the point, instead of 글쓰기 something long: I think 당신 should just be honest with her and tell her that 당신 don't wish to go. I'm sure that she'll understand you.
Wait, can't 당신 solve your own problems? Anyway, there is nothing wrong with camping...obviously from the other shit you've 게시됨 당신 need something that will get 당신 away from your stupid boyfriend and his stupid friend.
Do 당신 know the only time I've EVER done something for the holidays? Oh wait, the last time was never. I hate camping, but I would KILL to go with my family.
If it's because 당신 don't like camping, maybe consider it if 당신 haven't already, at least for your mom? :]
If it's because 당신 want to spend the holidays doing something else 또는 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 당신 were honest with her. :]
