I am a single mother - that is the reality.

I never feel lonely if I've got a book - they're like old friends. Even if you're not reading them over and over again, you know they are there. And they're part of your history. They sort of tell a story about your journey through life.

My mother was very ill when I was 18. She had a brain operation and then a nervous breakdown. It's very strange when you see your parents, who have always been your pillars of strength, suddenly become vulnerable. You don't know whether to be angry that they are not strong or devastated.

When I was growing up, I wanted to be my half-sister Lucy. She was 14 years older than me and was impossibly glamorous. I grew up in awe of her.

My parents instilled a really good work ethic from when I was little - if you want to have money to spend on holidays, you earn it. So I've always been someone who wanted to be able to survive by myself, but I think you have to let down the barriers a little bit - let other people in.
