Comedian Mental Health Issues

There's a lot of mental health issues in the comedian subculture. I don't know if this is a function of the fact that some comedians like some artists have substance abuse problems, just like some doctors do. Or if being a comedian requires a certain level of self-loathing. The comedians I know were at their salt almost all come from some kind of family dysfunction. There's something interesting about struggle, demons, misfitry, that if channeled properly can produce some gold.
