From his abusive childhood?I have a friend whose dad was an alcoholic and mom was an enabler and he DEFINITELY had issues and he was diagnosed with PTSD.(Sadly he died - but from cancer - completely unrelated.)I mean Jon Stewart yelling at you should bum you out, but maybe not make you so so miserable. Disclaimer: I don't know dude, but I know a couple of people who do and they all love him to death.
