Brandy Norwood seemed to have it all, but secretly she was struggling to live up to the perfect image she portrayed on ‘Moesha’. Her TV dad William Allen Young, knew Brandy was dangerously close to the edge. “I would see that she was tired… I think she felt responsible for carrying the show ‘Moesha’. To the point that, if it wasn’t right, she would exhaust herself to make sure that it was,” Young tells 20/20’s JuJu Chang. Part of that was her weight plunge, hoping she could look better being thinner. “It was destroying me. … But I looked great and that’s what mattered. And that was crazy,” Brandy said. Watch the interview tonight on 20/20 at 10 PM ET/PT.
