Hi biggestlosergirl! Welcome to this wonderful board. You know what? So many of us here have similar issues with food. We're all different and some people can come here and lose weight and never gain it again. That's not my situation though. I STRUGGLE. I also feel like there are so many things I'm capable of and I can control so many aspects of my life....but this one issue is my sore spot.
Let's look at the facts though: you went from a size 22 to a size 12!!! WOW! That is an amazing accomplishment. Yes, it happened in an usual place....a show. But, it was season 3 so you have kept it off for quite a while. That in itself is a major accomplishment! You should be extremely proud.
But yes, it would be so much better if you could get to your ideal weight. I don't have any advice because I'm a food addict myself. I have times when I can manage it for months and then one slip leads to a thousand more and then I'm up 20 lbs. What I can say is that the more I come here, the better off I seem to be. I hope you will find the support you need. Vent, share and visit often.
