Who are some of the celebrities, leaders, writers and other successful people who overcame depression?

My mother had major depression following a car accident and health crisis a few years ago and it worsened last year when she had my baby sister. I'd just like some inspiration. Can you please tell me about successful people who had serious depression but overcame it and led positive lives? I know of people like Virginia Woolf and Sylvia Plath who killed themselves because of depression and other mental issues, but I need to know about people who can give me a little more hope.
