Justin Bieber was "unhappy" with his life.
The What Do You Mean hitmaker admits there have been times where he felt as though he had "forgotten" who he really was.
He shared: "I went through a point of doing it for myself and doing everything in the industry for myself and I was unhappy because being able to do stuff for others is the biggest gift of all.
"I was robbing myself by not enjoying the moments where I should've been enjoying them and doing stuff for other people. I forgot what I was about, what my mom raised me to be. I veered off, and I got tainted."
And the 21-year-old singer also admits people have "taken advantage" of him in the past.
