(CNN) Justin Bieber is focusing on his mental health right now, not music.

In a lengthy Instagram post on Monday the singer explained that he sees the messages from his followers expressing a desire for a new album.

"I've toured my whole teenage life, and early 20s, I realized and as you guys probably saw I was unhappy last tour and I don't deserve that and you don't deserve that, you pay money to come and have a lively energetic fun light concert and I was unable emotionally to give you that near the end of the tour," he wrote.

Bieber released his "Purpose" album in 2015 and two years later ended his tour early "due to unforeseen circumstances."

At the time he posted a letter on Instagram to explain the tour cancellation.
