The artist shared: "Social phobia, panic disorder... I’ve had panic disorder ever since I was young.

"There were times when close people… Some of my closest friends have left me. People hurt me, so everything fell apart. I didn’t feel like I had anyone on my side or anyone who could understand me. So that’s why I completely fell apart."
