Kirsty Young's castaway is the agony aunt and writer Denise Robertson. She is, she says, one of life's survivors -- yet she seems to have had more than her fair share of tragedy; she's been widowed twice, dealt with financial hardship and lost a child to cancer. She's written dozens of novels and for more than forty years been an agony aunt on local radio, papers and television. She says: "There have been times when I've thought, just as I get things right, fate steps in and kicks the steps from under me. But then you pick yourself up again. When I started out, there used to be a joke, that one day I'd open a letter without saying, 'Oh I remember when that happened to me'."Producer: Leanne Buckle.
