The singer revealed that she has suffered sleepless nights since she shot to fame last year.
"My passion is so strong I can't sleep - I haven't slept for three days," she told OK magazine.
"I lie in bed and try to pray and breathe. I have a very overactive mind. I'm the sort of person who'd never take medication to calm myself. It's maddening. But I love what comes out."
The 23-year-old added: "If my destiny is to lose my mind because of fame, then that's my destiny. But my passion still means more than anything. For some people, fame kills it and becomes more important than the music or the performance.
"But for me fame is like rocket fuel. The more my fans like what I'm doing, the more I want to give back to them."
