I wish I had the answer. I too struggle with food. Sometimes I find writing helps, although not always. I am currently in therapy and working on some of my trauma issues (childhood sexual abuse, neglect, etc.) to get to the "root" of my overeating/binging. It's never about food. Food is the "solution" to whatever the "real problem" is.
You can check out some of my writing in the "Creative Corner" section.
