Girls Under Pressure
Jacqueline Wilson

The novel Girls Under Pressure is about an overweight girl called Ellie. Ellie thinks she looks awful, fat... DISGUSTING.
Her best friends are both drop-dead gorgeous and Ellie is sick of being the "ugly duckling". So she goes on a diet and she even starts to exercise... She's going crazy, her family and her friends try to stop her, but she doesn't listen to them. Then Ellie meets Zoë, an anorexic girl that almost dies because of her condition...
After seeing the harsh consequences Zoë goes through she decides to stop dieting.
This book was fabulous but it ended " suddenly ".
It's not as easy as described in the book to recover from an eating disorder. You can't be bulimic for a while, loose weight and then decide to "stop being bulimic". It's impossible... Recovering from an eating disorder usually is a really difficult and long process.
