London: Singer Nicola Roberts, who underwent professional help after suffering from depression, says therapies were 'too expensive' and did not even help her.

'No, it didn't make me stronger. It's too bloody expensive. I'd rather sit there all night thinking until I couldn't think any more, and then reward myself the next day with a pair of Louboutins.

But therapy did make me very deep, because I had to search for the reasons why these things were happening to me, she said.
