Ana

Ana refers to anorexia nervosa, an eating disorder. People with this eating disorder will often compare themselves to Ana, who they see as basically a physical manifestation of the eating disorder. She is often reffered to as 'my best friend Ana'. She helps the girls dive deeper into the eating disorder, telling them that they're still not skinny enough, and that what they're doing to themselves is right. She is often seen as perfect, the skinniest one could possibly be. You might also find pro-ana sites, which are hard to explain...
