The young woman claims her father, Carl, “keeps himself sick on purpose," and she and her aunt, Teri, believe he suffers from Munchausen syndrome.

“He’ll eat a pack of gum and then call the ambulance because his blood sugar is high,” Hilary claims, adding that her father sometimes calls 911 six times in a week and has been in the emergency room at least 200 times in the last year. “He has called me multiple times telling me he was dying; that he had, like, three-to-six months to live. That is not true. It is very unfair to me.”
