In answer to your questions, I'm from the US, and I like watching videos about eating disorders because I have one too, and I especially like watching binge videos because for the most part they allow me to look at vast quantities of food without feeling guilty and physically sick, and it usually reminds me that even if I were to binge I'd just feel bored and sick by the end. Also it helps to know I'm not alone with binging struggles as well. Being able to experience and relate to another person's joy and pain in regards to binging is kind of healing.
