I've been a single parent for a long time. It reminds me of being a waitress. As you walk back to the kitchen, requests come at you from all sides. You're doing the job of two - you have to be highly organised.

My mom, for all intents and purposes, was a single parent.

I don't think I realised how stressed I was, being a single parent. It was really, really stressful. It's not easy on anybody.

Passion has always been important to me. That won't change. What changes in a woman's perspective. I mean, I have two kids now. I'm a single parent balancing motherhood and my career. That changes the equation.

I think being raised by a single mother put me on the outside, and I would watch my mother's married friends and think, 'Why does she put him down in public?' or, 'Why is he so rude to her?' It seemed to me that there were very few marriages where the couple were genuinely in a supportive, loving partnership.

My mum Margaret was a single parent, but though life was a bit of a struggle she gave me every encouragement.
