"I had to be like, 'Do you want to keep being the kids? Or do you want to transition through that and be something of an elder statesman at 24?' Which I really feel like I am now, which I love, but it took a minute. I felt a little like, 'Oh no, I'm the kids?' "
The 24-year-old star recently admitted taking a break from social media had been "divine".
"It's been divine, I really enjoy it. I'm a shy sensitive person," she said.
"It's a lot of information, I realise how I was just pummelling myself with headlines and thoughts from other people all day and it didn't give me much room to have ideas or brainstorm things. I'm very grateful for that now."
But Lorde admitted there is one drawback to coming off social media - it is now much harder to keep in touch and up-to-date on her friends' lives.
She added: "The only thing I do think is that I underestimated how much of my friends' loves I kept up with on Instagram. People don't really tell you what they're up to, they just tell everyone via a story. That's how people stay connected. I really have to make friend dates. I've been calendaring people's birthdays now."
