How long have you been sitting in the darkness? You forget. You know you're getting hard to be with and you're crying every time you turn around. Oh my crazy baby, try to hold on tight. Oh my crazy baby, don't put out the light. And your hands are shaking something awful as your worries crawl around inside your clothes.

Oh, deeply vulnerable as a woman - to love someone not knowing whether they love me in return.

I make myself suffer with a lot of self doubt.

I have to say what I do is not easy and there are definitely moments where I feel inadequate to the tasks I've set for myself. And that's hard to feel - like you're giving your life to something and you can't really do it as well as you want to do it.

Being an artist is not exactly the most universally respected, or secure thing to do with your life. It can be frightening and you can feel that you're taking a lot of risks just with your own life, and your family's security. But the rewards outweigh those things.

There's so many different ways humans have used music to express the spiritual part of our nature and to connect us with the divine. So for me the pathway is through music.

Through music I've discovered other philosophies. Buddhism in particular is one that has always - whenever I've studied it and read about it, it's just been so true to me. And I do try to take some practices of that into my daily life. Whether that's meditating or trying to see the world from that perspective.
