The "Telephone" singer is so caught up with fame she no longer thinks sensibly and is so worried what her fans thinks she struggles to get to sleep at night.
She said: "I'm already crazy. I'm a fearless person. I think it creeps up on you. I don't think it can be stopped. 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. And my passion is so strong I can't sleep - I haven't slept for three days."
Despite her sleeping problems, Gaga refuses to take any medication to help her relax.
She said: "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."
