The `Yo-Yo` singer underwent professional help after suffering from depression in the early years of Girls Aloud but she doesn`t think it made her stronger and she would now rather help herself.
She said: "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, 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."
Nicola also says having therapy helped her become a counsellor to her Girls Aloud bandmates, Cheryl Cole, Nadine Coyle, Kimberley Walsh and Sarah Harding.
In an interview with the UK edition of InStyle magazine, she said: "I think it`s important, especially today, when judgement seems to be spiralling out of control. I`d use what I`d learnt on the girls too, a bit like I was the group counsellor. So if Sarah would be in a certain mood, or Kimberley said something out of character, I`d work out why and explain to them, `It`s because you`ve only had three hours sleep. You`re tired!` Although I think I could be quite annoying at times."
