Help, I've fallen and I can't stop eating

I have been attending weight watchers for 1 1/2 years and have lost 28 pounds. The first 20 pounds were easy. The next 8 were excruciatingly different. I have another 7 to go. Except I don't. I melted. It started with having to bake for a certain function. I should have said no, but I wanted to be a team player, so I baked. And I ate. And I ate. That was 3 weeks ago. And I'm still eating. I haven't been on a bender like this in a long, long time. I had gotten really far with changing my eating habits and thinking of this as a way of life, and not a diet. I am of the mentality that diets don't work. However, I'm a very short person and I was down to 117. It got to the point where I was following the program and not losing any more weight. For months. And months. Almost a year, in fact. I was so close, but it was feeling too restrictive and not fun anymore. I was starting to worry too much about everything that I was bound to collapse. And I did. Astronomically. I gained 12 pounds in 2 1/2 weeks. Now, I know a lot of that is water retention as I've stopped drinking as much water. I have been trying to get back on track for about 2 weeks and I just can't kick myself to do it. I stopped going to the gym, stopped going to meetings. Every day i say today will be the day, but I keep eating crap and to an extent that I just feel like crap all the time. I need to find a balance between eating healthily and feeling satisfied. Hopefully I'll get back on track soon.
