Boy oh boy... this is a tough one for me too. It's difficult for me to balance food as a reward, comfort, tiredness, anger or hurt. I don't know how it happened that eating went from just sustainability to "D, all of the above type answer". I work on it everyday... finding your writing about it helps.
I'm so happy to be any type of support! I think many of us have troubled food relationships. And maybe some of us genuinely don't understand our bodies' signals on the instinctive level? Or maybe the instinct is coping and food is the method. Hmm. Thinking about this.
