Food is sort of our "drug" of choice isn't it?

Is there something that perhaps triggered the binge eating? A situation?

Losing weight and keeping it off is a lifelong battle - one that I haven't managed to win myself. And any kind of setback just starts those old feelings of self-loathing and failure up again.

Look at this this way, you have still lost a lot of weight. That is incredible and still an awesome achievement! I managed to lose some weight 3 years ago, but I fell off the wagon and gained back even more.

My advice is, cut yourself a little slack - you are only human. Acknowledge you gained back some pounds and that it's okay. We all have setbacks once in a while. Then, promise yourself that starting Monday or whenever, that you are going to get back on the wagon. I found I did a lot better when I scheduled a "cheat day" every couple of weeks. That way I could look forward to indulging on that day with out completely hating myself.
