We've done a good job in this country in the last few years of reducing the stigma of mental illness, allowing millions of people to get the help they need. But we ought to be careful of the trend of "defining down" -- identifying just about any bad mood or idiosyncratic personality trait as a mental illness. That adds to the deepening lack of responsibility ("It's not MY fault!") in the culture and makes us take those truly in pain less seriously.
