Suzy says she came down with a “mysterious illness” 10 years ago that she claims forces her to constantly eat from the time she wakes up until she goes to bed. She claims that if she doesn’t consume a minimum of 7,000 calories a day, her body will start to convulse and tremble.

“It’s so painful watching Suzy go from this vivacious, gregarious, social, beautiful girl to what she is now,” says Louie, noting that she has put on weight and that her self-esteem has been “completely annihilated.”

And later, what does Suzy’s friend, Maxine, say she believes may be contributing to Suzy’s illness?
