Emotional eating is a very tough issue. It can pop up out of nowhere when you least expect it. the first year following surgery is not usually a problem. But those previous "eating disorders" will creep up on you and slap you silly.
Continue to do your research. Reach out for help. Use every resource available...including this wonderful group of people!
I've had my share fair of emotion eating issues. I'm not much for group support...I just don't do well in group setting. That said, there are many other options. I am constantly researching and trying to find answers for myself. Coping for an entire lifetime isn't easy...but you can do it.

thank you

If it's just mindlessness, take time to focus on your meals and snacks. Make a ritual of it. Prepare it, sit at the table, no TV, no cell phone, no internet. Pay attention to each bite, put your fork/spoon down between bites.
I practiced this early on to prevent the dreaded foamies. Now, I practice it to keep myself mindful of how much I'm eating and focus on healthy choices. Since I eat so little nowdays, it's really important to use fresh, healthy ingredients. But I can now afford one, small, lean, steak, a nice pork chop, a salmon fillet and 2 chicken breasts, for a weeks worth of dinners and lunches, instead of a 3 lb. chub of hamburger, a Boston butt roast and a big pack of chicken thighs with skin.

What works for me? Journaling, counseling to work through issues on why I turn to food, pre preparing meals and snacks, and EFT tapping. Even at 5 years next month I still have to stay on top of things. I recently found a new therapist who is wonderful! In just 2 sessions so far I have made some good changes. Her focus is food/weight/eating disorder and body image related. Keep reading and learning! Geneen Roth and Doreen Virtue both have very helpful books. In Doreen's book on cravings, I recently connected a craving to an emotion and it was right on. She has lists of foods people crave and the emotions or issues attached to them.
