Telling someone with Anorexia to “just eat” is like telling someone with Depression to just “be happy”. Someone with Bulimia to just “stop purging”. Someone with Schizophrenia to just “be themselves”. Someone with Bipolar to just “stop being moody”. Someone with ADD to “stop attention seeking”. They are all mental disorders and they are all very hard to deal with. It’s not easy. You can’t “just get over it”. It’s more complicated than that, and you should love your friends enough to understand that and support them. Not give up on them and tell them to stop being silly and help themselves. These things stay with you for life. It’s not something to just end when you choose. They are serious diseases, not fashion statements.
