I, personally, went through hell every DC or CA. Not because of the sheer drudgery but because of the fear of large crowds. It was all that I could bear!
You either need to tell her the truth about how you feel, or lie. The truth is better, but if you said what you really feel about the dubs, you would probably find yourself in front of a judicail kangaroo court.
Although I informed persons that sometimes I just couldn't bring myself to go, because I would just panic and run out, they still thought that I was eeeevil. Nice support, no? (I still suffer from this to this day, BTW) Apperantly, I wasn't relying on god enough and was weak in faith. If you want to lie, that excuse can work... but the truth usually works better.
There are no easy answers, unfortunately. You will be a 'pagan' if you don't go. If you're smart, you will hold your ground.
Good luck in your decision, and welcome to the board.
