Hmmm. I can,as a former sufferer, confirm that depression doesn't make you an exploitative, attention seeking, fame hungry twit with a saint complex. Having said that, I don't think he's the full picnic,I think he's a fame addict and it defines him so much to the point where he'll happily exploit his own family members to fill his needs. He also need to adress his caffeine issue.
I've had depression off and on for most of my adult life, the last thing it makes you is a fame whore with a saint complex, I could barely get out of bed, let alone sell my soul to the media. I think he is not quite all there, but narcissism is a much more accurate description.
