Not really surprised about this. A look back at history tells us many authors, playwrights, poets, and of course, musicians have suffered the same "demons".  I've come to the belief that the most "creative" individuals, are also the most fragile.

In a newly-discovered interview recorded at the height of his fame, folk legend Bob Dylan admitted being suicidal and having a heroin addiction.

The singer-songwriter was taped by his friend and biographer Robert Shelton on a plane journey in March 1966.
