I can't even put into words..

This is disgusting. Just like the mental patient costumes this "Anna Rexia" halloween costume is not okay. Anorexia is a mental illness and a very serious one at that.

I saw a post on tumblr once about a person whose family member got diagnosed with cancer and was told he had an 87% chance of recovery.

Only around 46% of anorexics completely recover and as many as 1 in 5 (that's 20%) of anorexia suffers will die prematurely. It is a deadly disease just like cancer is.

I understand that halloween is about dressing up and its just a 'bit of fun' but you wouldn't dress as a person who has a physical illness as opposed to a mental one.

I am actually disgusted. Stick to being witches or whatever it is people dress up as for halloween.
