The 31-year-old singer said people warned her to take such a long break because it might ruin her career, reported Digital Spy.
"People were like, 'You're crazy, you shouldn't do this. It's a bad career move'," she recalled.
"(I said), 'It's me or me mental health'. Honest. My gut instinct was like, 'It's enough'. For the first time since I wanted to be a popstar, I didn't have any fire in my belly. Without realising it, I had gone to a dark place. I needed a reality check and get some real feelings back," she said.
"I've got 11 nieces and nephews, and I've been through every single stage with all of them. I had three of them down a couple of weeks ago, and I love having them. But it's also nice saying, 'Bye! Go see your mam and dad now!'.
