I said this in chat earlier man. From what I have seen through the news services around the world people are discussing these issues, depression, mental health and addiction. In Australia, every time they mention him, which is a lot they always mention a phone number for people to call if they feel they need to. I for one think this is fantastic and Robin Williams is still helping the world, even in his death.
*UPDATE*
Police have now reported officially that Robin Williams committed suicide. Williams firstly tried to cut his wrists with a pen knife and when this failed he used a belt on his door knob to asphyxiate himself. A very sad ending indeed to a comic genius who made everyone in the world laugh and not to mention what he did for the troops and causes through the world.
