Acting legend Garry McDonald is a man on a mission. He wants to educate the public about an urgent and poorly understood mental health problem. McDonald has suffered from anxiety since his 20s but he never understood his condition until it triggered a major and very public breakdown in the 1990s. He sought help in the form of Cognitive Behaviour Therapy, a treatment which trains individuals to examine negative or unhelpful thoughts. And gained a new lease on life... In between roles, the veteran actor has campaigned passionately to increase awareness around anxiety and reduce its stigma.
