How is Eileen Dunlop described in the novel, Eileen?

Twenty-four years old at the start of the novel, Eileen Dunlop is described as a quiet, self-absorbed girl, who is deliberately malnourished and living with her alcoholic father in the quiet town of X-ville, a generic New England town. She spends the majority of her time within the confines of her own mind, alternating between self-loathing, being ashamed of her body, and engaging in fantasies of either escaping X-ville or falling into a relationship with Randy, a corrections officer who works at Moorehead.
