Years ago I wrote a free workbook, Triumphant Journey, on how to stop overeating and recover from eating disorders. I'm in the process of creating a new edition for this site.  You can find the original version of Triumphant Journey on Self Help Magazine. Marlene Maheu, the founder of Self Help Magazine generously published the book online in the early 1990's. It's always been available, for free, and many people with no access to eating disorder treatment have found it helpful.
