We all got older, and we'd tell our children things like, 'Mommy used to be in a famous rock band,' but they didn't believe us. Part of the reason for our reunion was to show our children what we did to make the lives they have possible.

I was so young when I got so famous, and then I kind of put up a wall around myself. I didn't really want to show people any fragilities or fears; I was trying to be this tough person that I felt was expected of me.

When the Greatest Hits came out and we did that tour, I just felt I wanted to take a break, totally. Probably because, as well, I was so young when I got famous. I did album, tour, album, tour, album, tour, then I had a public nervous breakdown where I just lost tons of weight.

I enjoyed living in Canada, where my husband comes from, because I was treated like any ordinary person. I became a volunteer at my children's school; I went into the classroom. It was very grounding. I got sick of being famous.

I was so famous that I couldn't leave the hotel room. I remember looking out of the window at all these fans but just feeling so isolated.

Growing up, there was a lot of pressure for women to be good-looking, but my mum was very strict, and she didn't allow me to wear make-up. Looking back, it was good for me. It slowed me down from becoming an adult too quickly.

My mom always had a softer spot for boys, as a lot of Irish women do. If you were a girl, you'd have to sing or wear a pretty dress. But boys could just sit there and be brilliant for sitting there and being boys. It makes you that little bit more forward. Pushy. I was singing, always.

Everyone at school knew I wanted to be a singer. I'd always be banging on the piano playing my new song. The teacher would gather us round, and the whole class would listen.

I didn't get a lot of attention from my dad when I was young. That's a big part of it for girls. Because your dad is the first love of your life. If he doesn't put you on his lap and give you a pet, you do end up not really liking yourself that much.

As you get older, it's good to open up and acknowledge that everybody has their scary moments, their negative moments. And in order to move on and find comfort and hope, you have to stop running from the darkness and face it. And when you face it, it's not that scary at all, and sometimes it actually turns around and runs away.
