Billie Eilish Addresses the Moment She Felt She 'Lost It,' Admits She's 'Not Been Doing So Great'

On growing up, evolving as a person, and learning to set boundaries:

“When I was 17, I was like, I found it. I found the person I am, forever. This is how I’m going to do it. I found all the ways! These are my boundaries. These are the things that make me happy, and this is my recipe for how I’m going to make music and be happy. Then I grew up a little, and suddenly life was like, These aren’t going to work. You’ve got to change. You’re not that person anymore.”
