I saw a link to this website on twitter that may be useful to people in all stages of recovery. This website, Centre for Clinical Intervention, offers an "Eating Disorder Workbook" with links to a multitude of interactive .pdf files to help you work through symptoms, identify and manage triggers, etc. There are two different workbooks. The second one, Part B, was most helpful to me, especially Module 7 "Relapse Prevention." Here are the links:
Overcoming Disordered Eating - Part A
Overcoming Disordered Eating - Part B
Hope this helps!
