I've been doing an online program on the reasons behind emotional eating and binges. It's very good if you want to pay money for 12 weeks of online "shrink" sessions.

There is a free session which asks questions then gives very informative info on why we binge and about bad habits.
The sessions go more in-depth and looks at replacing bad behaviours with good ones. I'm up to week 6 so far and it's been really good for me.
