During an interview with Arizona’s ABC-15, rapper DMX opened up about his struggle with bipolar disorder which causes mood swings and severe depression.

 
He explained that he used to be able to distinguish X from Earl Simmons, but now has difficult separating the two. “I used to be really clear on who I was and what characteristics each personality had. But I don’t know at this point. I’m not even sure there is a difference…”
 
DMX busted on to the scene after the release of his debut major-label single Get At Me Dog. He was the second rapper to have two albums- released in the same year debut at number one on Billboard's Top 200, the first being Tupac Shakur.
 
DMX is currently working on an upcoming album Redemption of the Beast that he plans to release by the end of the year.
