Confronting a Narcissist means there is no hope. They refuse to listen, they refuse to understand, they refuse to allow you to express your views. All they want is to silence you, abuse you, tell you it's all your fault. I believe the best thing to do is to walk away. You can't reason with evil.
Where it was once thought that socio-cultural factors (e.g., media, parents, peers) and problems with self-esteem were the main causes, it is now understood that Anorexia is more of a brain disorder. Those other factors may contribute to an eating disorder-they are not the cause- There’s genetic susceptibility, and there are environmental stressors. But it’s definitely not a matter of free will—no one chooses to become Anorexic. Like any other illness, Anorexia is biologically based.
