As a group project I have to come up with an idea for a support group. My group chose teens with eating disorders. We have to come up with an activity to demonstrate to the group. Any ideas?

I don’t know the answer myself. But I think I know two bulletin boards you can go to, to possibly get an answer:

#1 - the "Something Fishy Website on Eating Disorders"
http://www.something-fishy.org/
Click first on "Online Support" on the left;
then "Online Options", and then
on the "Remember It Hurts" Web Board (perhaps in the "Anorexia and Bulimia" message board,
or try one of the other online communications.

#2 - The National Association of Anorexia Nervosa and Associated Disorders, Inc.
http://www.anad.org
Has online Discussion forum (click on "Discussion" on menu board across the top. Then post to "On My Mind Today" message board.).
They also have over 125+ free local ANAD support groups, and they assist individuals in the formation of self-help support groups. They also have a telephone helpline for all those affected by eating disorders. Scope: International
Founded: 1976
Telephone: 630-577-1330
Email: anadhelp@anad.org

Sorry that I don’t have the answers. But I think one of these two might provide ideas. I’ll try checking possible other places, and let you know if I uncover anything specific.
