I haven't explored too much of this site. The website seems to be more geared towards sufferers, but does have some information for parents. I spent most of my time in the parent forums. I found a lot of support from parent to parent, but it wasn't a highly active community. I also noticed that a lot of the parents there were not very involved in their children's recoveries. It seemed like a lot of the treatments those parents talked about, still involved blaming the parents or convincing the patient to want to eat.
This is probably a good place to find support, as long as you do so with your eyes wide-open.
