Re: Elyn Saks

Elyn Saks was interviewed about what schizophrenia really is. "A common misconception is that we're unable to care for ourselves and that's not true," she said. "For some people it is, but not for all of us. We can have relationships –romantic and friendships. But we often don't see that (in the media) because of the emphasis on sensationalism and 'othering' us."
