Kanye West Breaks Down As He Opens Up About His Mental Health

'When you hear about slavery for 400 years ... For 400 years? That sounds like a choice.'

Last May, Kanye West hit the headlines with these controversial remarks, given in an interview with the US media outlet TMZ.

These comments shocked his many fans, and Kanye has tried several times to justify his extreme opinions, often rather haphazardly. While in Chicago, the rapper finally made a clear apology at the microphone of a local radio station.

'I don't know if I properly apologized for how that slave comment made people feel, so I want to take this moment right now to say ... I'm sorry for people who felt let down by that moment,' said Kanye, his voice shaking.

The artist also evoked the subject of his mental health, as he revealed last June that he has bipolar disorder, which he refers to as his 'super-power'.
