The typical Holiday downer

Ok so today is Christmas obviously and I have enjoyed 23 cookies, 3 chocolate bars, a few yogurts, and a 3,000 calorie main course meal. Delicious, i know, that's the problem. I'm a tall chick, used to weigh in at 128 last spring and was a track super star. I'm not allowed to run anymore due to injury and weigh 142..sigh. I want to eat less, but food is so, well, like I said, delicious. It's not that I'm fat, because I'm not, but 142 is quite a downer when you used to be 128. Sucks to suck I guess. Can anyone relate?
