Hang in there Robin!! It's great that you posted here to get some support. Probably why you have been so successful in the past.
Here's my 2 cents:
I think you are right to worry about it continuing. We all know that we didn't plan to put on X amount of weight. It came on little by little, while we weren't paying attention, when we had slip ups that turned into lifestyle changes that were distructive.
But, you know better now. You've come such a long way. You've reached out to get some support and that's what is important. In the time that I've been reading posts on 3FC, you've always been the one who is encouraging others. You know what to say, what works, and have helped so many. I have been so inspired by you! This little bump in the road won't derail you!!! I know it won't!!! You're too important to all of the others that frequent this wonderful place and you're too important to yourself to let it go!!
