Robin Williams suicide is a creepy thing. Part of me finds it difficult to believe it was a suicide, though i have no real way of knowing. 

Did you see his Diagnosis and med history? What about his coke habit? 

He's one of the suicides that makes sense if you ask me, following the obvious suicide of Jim Carrey within the next 10 years. He's one who lived a life of suffering, and you can see it in his works.
