Taylor Swift starts panicking if she hasn't written a song for two weeks.
The Love Story singer insists she's always writing new tunes and creating lyrics but there are times she worries that she has lost her magic.
She tells Los Angeles radio host Kidd Kraddick, "Every time I go about two weeks without writing a song I sit there and have, like, an anxiety attack and... I feel like I'm never gonna write a song again, and then I have nightmares about it and I stay up and I can't sleep and then I end up, like, writing a song the next day.
"The thought of never writing a song again is the scariest thing in the world; It's, like, one of my top fears."
