“Like, man, is this pain ever going to go away? It was so consistent, the pain was so consistent.

“I was just suffering, right? So, I’m just like, man, I would rather not feel this than feel this.”

Justin became a megastar at age 16 when he released his debut album, however, he said he was shocked at all the “mean” comments he received as a teen, with trolls claiming he “looked like a girl.”

He recalled: “I had no idea that I would get sucked up by all this stuff. There were just so many people who were so mean. Random people who were like, ‘You suck,’ ‘You look like a girl.’

“I would shake it off and act like it didn’t bother me, but that stuff bothered me and then it affected how I acted and how I treated people.

“It’s like thus ongoing cycle of like, hurt people hurt people. I was just this young kid.”

Justin, who was arrested in 2014 for drink driving, also once found himself dating another rising star: Selena Gomez.

The former pair were first linked publicly in 2011 and dated on and off for years until their final split.

Recently, fans pondered whether Justin’s latest tattoo of a rose on his neck was done in honor of Selena.

One fan wrote: “The rose has a freaking S in it. An S for Selena!!! I can’t stop screaming!!”
