While Gigi has been forced to defend her modeling career, Bella says people "are really mean" to her when it comes to her struggle with Lyme disease, an illness that her mother Yolanda
and brother Anwar Hadid also battle. "They always say that I don’t have what I have -- but it’s taken a toll on my life since I was 15," she shares. "I’ll occasionally get comments now like, ‘How do you have this disease if you’re working every day?’ But I didn’t want it to hold me back anymore. I’m still 19; I still have a life and things to do."
