Andrew Solomon's TED Talk: Depression, the Secret We Share

Andrew Solomon's TED Talk "takes you to the darkest corners of his mind during the years he battled depression.

"The opposite of depression is not happiness, but vitality, and it was vitality that seemed to seep away from me in that moment. That led him to an eye-opening journey across the world to interview others with depression -- only to discover that, to his surprise, the more he talked, the more people wanted to tell their own stories."
