In an interview with Pitchfork, the singer revealed how music was his 'channel' for speaking about his battle with mental health issues.

"I suffer from depression and some days I wake up and I’m like, 'F***, I wish I didn’t wake up'. That was part of why I moved to California, trying to get away from the place that was doing that to me, and the people I was around. I realized it was just myself — it’s a chemical imbalance in my brain," he said.
