The singer-songwriter told XFM that she got tired of playing tracks from her 2007 debut Made Of Bricks.
Nash said: "Loads of stuff happened and it was quite extreme. I was really exhausted and frankly quite tired of it. I was sick of doing gigs.
"I was like, I don't like playing these songs, I don't want to do anything, I want to go home and unpack my suitcase and get back to normal life. I wanted to pass my driving test and get back to normal life!"
Nash releases her second album My Best Friend Is You on April 19. The album was preceded by single 'Doo Wah Doo'.
