"I've always been someone who wants to win with who I've come up with," the 31-year-old said.
"I love the idea of doing things as a team, you come with your people.
"Sometimes along the way, there's a parting, there's people going in different directions, and as I'm getting older I'm learning to be at peace with that and letting go and moving on.
"My music's always been a space for me to speak about those things in a way that feels authentic and that's honest.
"I think that's part of my healing."
