Most people (i would hope) realise that anorexia is a disorder and not one you have a choice in.
I have never seen anybody claim to have the 'mental' side of the disorder yet not the physical. I found this during a browsing session on LJ:
"My name is ***** and I am ana with b/p tendencies.
I'm not your skin and bones anorexic, I'm actually very overweight for my height, but I have the mindset of a person with severe anorexia."
How can you have the mindset of a severe anoretic yet be overweight? This makes no sense to me.
Sorry if I am ranting... I have had too much gin.
