'What Do You Mean' hitmaker Justin Bieber has revealed that his personal lows started to really influence his songwriting and he was creating music that was quite dark at one point. 

He told Access Hollywood that he ended up "scrapping" a lot of tracks because they were reflective of the bad place he was in mentally:

"When you're in kind of a bad headspace, you're writing about being in that bad headspace. It just really doesn't really match up with what I'm doing now, so we scrapped a lot of songs and we've moved in a pretty different direction."

As previously reported, Bieber also opened up about feeling alone and confessed that he was afraid to let his guard down for a long time after being hurt by friends and people in the music industry alike:

"I was really in a weird place. I was in the industry so young and you have so many people that you lean on and trust... I just didn't have my guard up, so I got my heart broken a bunch of times by friends (and) people in the industry. After a while I was like, 'You know what, I'm not gonna open up to people anymore; I'm just gonna be guarded'."

"I was really about myself for a while and then it just got to a point where I was, like, so unhappy, I was so lonely, I felt so alone. I was so closed off to everyone, even my friends. I was like, 'I can't trust anybody', so I started just acting out, doing whatever I wanted to do."
