Pop star Justin Bieber has opened up about achieving too much too soon and the negative effect the fame had on him. In a lengthy Instagram post, the "Sorry" hitmaker said at the age of 19 he started doing drugs and "abused all my relationships".

"I started doing pretty heavy drugs at 19 and abused all of my relationships. I became resentful, disrespectful to women, and angry. I became distant to everyone who loved me, and I was hiding behind, a shell of a person that I had become. I felt like I could never turn it around.
