it's like depression in the mental sense. you kinda have to fight it. You'll fake a smile and stuff, just like they'll eat in front of you, but then sob behind closed doors. Most anorexic people don't want people knowing because it's harmful to themselves and most know it. But it's always best if someone does because the throwing up food isn't good for you. And no, they won't eat. They're almost scared of eating because they think it makes them fat and unlovable. They'd rather destroy themselves
