Hi there, I have all these same issues and I won't get into details because they are really so similar to all of you.
What I am feeling right now, though, is incredible anger towards a society that places so much emphasis on being thin. That combined with a f-ed up attitude towards food - how much weird processed "food" we invent, our puritan values surrounding denying food instead of just enjoying it - has deprived all of us of a joyful, simple experience of food. Obviously in the end I need to take responsibility for myself and what and how much I eat, but I think we need to acknowledge the context in which we all live and were socialized in.
I think someone else mentioned how it helped to blame her mother

. Yes, I am angry that I grew up with a beautiful, healthy mother who hated her body and micromanaged every calorie that went into it and went through periods of noticing everything I ate. Of course I was going to start sneaking food. I saw (and still see) scarcity of food as a mindset that would stay with me always - this imposed on the reality of food EVERYWHERE.
I've had 15 years of various dietary changes superficially aimed at "being healthier" but really about losing weight even when I was already thin. Cutting out meat, sugar, dairy, wheat .. and it made me feel good and lose weight, sure, but it's all based around denial and viewing food as 'bad' .. something I don't want to keep up for a lifetime. So as soon as I'm not applying these 'no this-or-that kind of food' top-down rules, I make up for all the time I was denying myself by binging.
I've been scared to do it before for fear of gaining a ton of weight, but what I need to do is give myself permission to eat anything, anytime. Stock the house and car with all those 'bad' trigger foods so reassure myself that they will always be there - no feast and then famine, a never-ending supply. I know this may seem counterintuitive, but after 15 years of just trying not to have sugar or whatever around me, I know that is not a long-term solution. I want to live a life surrounded by good food, and not be afraid to eat it.
Is anyone else approaching it this way, rather than denial and avoidance?
