Kanye West has claimed American people are 'completely bullied' by critics to think certain things in an interview with David Letterman. 

The 41-year-old rapper sat down with the veteran host on his Netflix show, My Next Guest Needs No Introduction, on an episode which streamed Friday.    

He claimed: 'We're pushed into it. We're driven crazy. We forget who we even are. 

'We're driven to like a certain type of career that we're supposed to be. We're, like, completely bullied by the media, both celebrities and the masses, to think certain things and have group thought.'

Kanye, who was diagnosed with bipolar two years ago, compared the condition to  having a 'strained brain.' adding. 'We're all dealing with mental health.

'Like, 'Oh yeah, damn right we're going crazy. I'm the most famous person with [bipolar personality disorder] and I've only experienced it for two years. What about people that's been experiencing this since they were two?.'
