MD, even quite late into recovery I had certain safety things I needed if I was eating around others. Like I needed my back against a wall. There is no doubt that my mind linked eating with threat.
There can be other reasons too though and I have had some of them. Such as feeling shame that you have given in and somehow feeling it makes you look vulnerable. That it feels terribly private and almost as if one is undressed.
I would be really careful about the girl at group. For the both of you. Maybe you could agree to not mention certain things to each other. I think the person at the higher weight is particularly vulnerable to being damaged by the interaction. You don't want to be where she is. It doesn't feel good and it is a slippery slope and you have quite enough to deal with already.
