Can a severely mentally ill person become a doctor - Hmmm.

I think it's possible, yes. If you can learn to manage your illness well, cope with pressure, utilize a support network etc., and have the academic mindset and functionality to see you through, then, sure. Why not. People achieve all kinds of goals all the time with all sorts of different psychological or physical challenges. Look at the film A Beautiful Mind starring Russell Crowe - about a man struggling with schizophrenia whose work goes on to win him a Nobel Prize in economics, I think it was. Or that guy who climbed Mt. Everest with no legs. What about Helen Keller or Howard Hughs? [Howard Hughs struggled toward the end though, but he achieved a lot] You have to be honest with yourself as well though, and know your limitations.
