I'm on the receiving end of hearing the news. I found that
www.something-fishy.org helped explain a lot. It also had support forums for those who were somehow linked to a person suffering from an eating disorder.
It wasn't a shock when I got the news. It was difficult to know what to do...how to help... how to listen...how to keep the pieces together with three kids.
Not sure that my comment helps, but I believe that the web sight gave me an outlet to learn things I could never have known...
