am i the only one?

I have gained weight over the holiday. I really didn't think it would happen, I really thought I would avoid it. Well I thought I might gain like 2 lbs of water weight but it is more and I don't want to talk about it :)I just feel gross. I went to the gym last night and did a Jillian Michaels workout and it was tough, I've gotten out of shape. craaaaap. I guess now is the time to do the post holiday melt down, that's what it's for, right? And I've signed up for 2 races for next year already. Woman's triathlon in May and a half marathon in July. I'm excited. And this year, non of my goals involve weight loss. I just don't feel like it's necessary. I know I'll do another boot camp and I have 2 races to train for so I don't feel like I'll gain any more than I did over the holidays and there is no other way to go except down?
