Justin Bieber: I get depressed

Justin Bieber feels so depressed and isolated that he wouldn't wish his life on anyone.

The 21-year-old pop star is attempting to reinvent himself after a difficult period which saw him split from his long-term girlfriend Selena Gomez, have multiple run-ins with the police and be accused of smoking marijuana. He's back with a new album called Purpose which is out on Friday (13Nov15), but insists fame is not what it's cracked up to be.

"I just want people to know I'm human," he told NME magazine. "I'm struggling just to get through the days. I think a lot of people are.

"You get lonely, you know, when you're on the road. People see the glam and the amazing stuff, but they don't know the other side. This life can rip you apart. (I get depressed) all the time. And I feel isolated. You're in your hotel room and there are fans all around, paparazzi following you everywhere, and it gets intense. When you can't go anywhere or do anything alone you get depressed. I would not wish this upon anyone."

Justin feels many of his problems have been caused by the way he is portrayed in the media. He was signed by Scooter Braun and Usher at just 13 and worries that because he was pushed as a "wholesome" boy with "nice hair", any mistakes he made seemed especially bad. His image became something he had no hope of living up to, with the star explaining: "When all this happened people were like, 'Woah, let's rip him apart'. If you see Gandhi roll up a blunt (marijuana cigarette), it's different to seeing Ryan Gosling roll up a blunt. You wouldn't give Ryan Gosling a hard time."

The Canadian star even compared himself to late singer Amy Winehouse, who died in 2011 aged 27 following an alcohol binge. She had battled addiction throughout her life, which is documented in a film called Amy that moved Justin when he watched it.

"I watched the Amy Winehouse documentary... and I had tears in my eyes because I could see what the media was doing to her, how they were treating her," he said. "People thought it was funny to poke her when she was at rock bottom, to keep pushing her down until she had no more of herself. And that's what they were trying to do to me."
