I can understand why some people might look at me and say, 'What's she got to be depressed about?' I get that a lot in Britain, where mental health issues seem to be a big taboo.

It's much easier to write when you're sad. But you can end up isolated and depressed because you almost need to put yourself in that situation to have that angst to write from.

Happy songs are very difficult to write. How many truly great upbeat songs are there?

It's not very often that I like new bands.

I exercise three to four times a week, doing the Tracy Anderson Method, which involves toning and strengthening our small muscle groups.

I think where men are credited for being strong, women are divas. I just think it's such a cop out.

I know my music probably isn't going to matter to the public after I die, but that doesn't mean I don't have something to offer.
