Hi... I am definitely an emotional eater and can see that a support group for overeaters would be good.

Count me in for at least occasional support... maybe more. And please always feel free to PM me, if you're needing to process an issue that is pushing you to eat.
I understand the concern about OA. There can be very strong sentiment against carbohydrates there...

But you might be able to find a sponsor or group that is supportive of the whole-food vegan lifestyle. I'd give it a try, at least. Who knows? Maybe there is a phone group (OA) specifically for vegans! (Something to look into...)
One good thing: it's basically impossible to overeat broccoli, carrots, and other colored veggies... So, maybe they could be "go to" foods for you when you're stressed. Teas are good, as well... chamomile is calming... so is peppermint...
Okay, you're on your journey. You're not perfect. You're learning and growing, and if you just keep putting one foot in front of the other, you WILL get to where you're going. Lots of people "relapse" (in a variety of addictive situations), and the experience can actually be a part of recovery.
All that said, John Allen Mollenhauer, an amazing trainer and entrepreneur who brought me to Dr. McD, once told me something that I found so freeing. He said, basically, that there's nothing wrong with eating for emotional reasons. Don't attempt heroics if you're really upset or stressed, other coping strategies aren't working, and you really, really want to eat. Just eat highly-nutritious whole food! Maybe you won't lose as fast as you would have, otherwise, but at least you won't totally sabotage yourself....
It's amazing what a little potato can do for the soul... it's such a serotonin booster!
Big Hugs,
Michelle
