The comfort binging brings is so very temporary - mere minutes - compared to the time it takes to take off binge pounds. And it could not be more counter-productive to what you want, which is to not be fat anymore. So don't do it! You'll be much prouder of yourself if you stay strong.
As for the pictures, I'm not much help there because I feel the same way about my pictures even now and I'm only 20 pounds away from a "normal" BMI. So take comfort in the fact that you are not alone. Keep taking care of yourself and eventually your body will catch up to your mental image. Hugs to you!
