I dont know anyone personally who has an ed and thats why I came to the forum to see if I could relate to anyone on here. Most people with eating disorders are very private and many people would never know that they have an issue with food. A lot of people I know and have known would never have known that I spent hours at a time throwing up, how could they? Having am eating disorder is something which many people struggle with alone, so many people with ed's dont know each other in person but on the internet were they can get and give advice to others. Many people with eds just want to know that they are not alone, they dont want help.
If a person is getting treatment for their ed then it is very possilbe they will be introduced to others with eds maybe to help them in coming to terms with it or something, I am really not sure.
Sorry I wasnt much help but maybe others will post a reply that will be of help to you.
