Janet was just twenty-five years old. She had a great job and seemed happy. She committed suicide. In her suicide note she wrote that she felt "un-pretty’ and that no man ever loved her. Amy was just fifteen when hospitalized for eating disorders. She suffered from both anorexia and bulimia. She lost more than one hundred pounds in two months.
