It sounds like your resources are limited for getting support in your local area, so I wanted to recommend looking into the Pound of Cure nutrition program, which is run by Dr. Weiner in Tucson, AZ (he also has a couple books and YouTube channel with bariatric educational information). It's $49 a month and allows you to attend unlimited online support groups with their dietician and peer leaders, as well as a few sessions per month that are run by Dr. Weiner. I've subscribed for a while and go to at least a few of the groups per month as my schedule permits. Many times there will just be a few people in the group and you can really get a chance to ask your questions and get some good advice.
Just for example, there's a group for the first year post-op, for emotional eating and stress management, and even one for surviving the holidays and travel. They've been in this business for many years and I'm betting they could think of dozens of patients who felt exactly how you do right now but went on to be successful.
