James Packer has opened up about his mental health struggles in a candid interview with Robbie Williams, reflecting on the 'trainwreck' of his split from Mariah Carey in 2016, which he describes as one of the darkest periods of his life. The billionaire, who has battled bipolar disorder, stated that money does not guarantee happiness and emphasized the importance of addressing mental health issues. Packer's interview is part of a broader special on mental health airing on 7NEWS Spotlight, coinciding with the release of a new book, 'Profiles in Hope'. He candidly shared that he is not seeking sympathy but rather aiming to help others with similar struggles. Williams echoed Packer's sentiments, highlighting that mental health challenges can lead to isolation. Packer has also made significant contributions to mental health research, donating $7 million to support initiatives at the University of NSW.
