You must eat in order to live therefore it is imperative to make peace with the issues that make you want to overeat.
Addiction is usually about two things, either escape or pleasure.
Eating can serve both purposes. If we eat for escape, there is often some painful part of our lives or the way in which we view ourselves that we would rather not deal with. For me, food addiction and my bulimia stemmed quite simply from shame issues. I felt a great deal of shame deep in my core and could never effectively deal with these feelings. Part of the reason I was unable to get a grasp on my shame issues is that I was totally unaware that they were at the core of my bulimia.
