I can easily see how she got into this state. Her mother is fashion industry royalty where thin, thinner, thinnest DEFINES who you are. She is surrounded by fashion industry people who obsess about weight and judge you for it.

While she remains in that environment and with those people, including her monstrous mother, Allegra doesn't stand a hope in hell of dealing with her illness.
