3. Michael Phelps
The 28-time gold medal winner across five Olympics is the most celebrated player in the history of Olympics. But that did not make him immune to mental health crisis. The US swimmer had deep bouts of anxiety and depression and even contemplated self-harm as revealed by him in an interview with CNN. He not just conquered his illness but now runs a foundation called the Michael Phelps foundation and the Boys and Girls Clubs of America to help others.
