The 'Great British Bake Off' winner has opened up on how her life is affected by the anxiety triggered episodes and over a year ago she had a bad attack after she received parsley instead of coriander in a delivery.

Speaking to Eamonn Holmes and Ruth Langsford on 'This Morning', she said: "Yeah it's something that I don't think is ever gonna go away. Sometimes, for example, I had a food shop come in about a year-and-a-half ago, and this is something I always remember and I ordered coriander and they gave me parsley. That was it. I had a panic attack just, it was bubbling away all day, then it just rose to the surface and I said, 'Move the kids away, I can't have them see me like this.'

"It feels breathless and it feels like you're going to die - it sounds so dramatic but it's not but that's exactly the feeling you get. For me its patterns, so if I'm used to doing something a certain way and somebody says you have to do this a little bit different, I don't know if it's something that will ever go away. I haven't had treatment for it, I use my baking and my writing as therapy and expression. I can just stop and think 'I can do a little bit of writing'."

Nadiya, 34, is releasing her second novel 'The Fall and Rise of the Amir Sisters', which is a follow up to her first fiction book about faith, family and the sisterhood between four siblings.

Nadiya - who has three sisters and two brothers - has written about sex in her latest tome and she admits the racier parts mean that she can't let her mother read the book.

The TV cook - whose family are Muslim - said: "The mum in the book talks about sex quite a lot and, I'm even saying the say the word and I'm thinking I can hear my mum, she would be rolling her eyes, I can feel her eyes rolling already because we don't even say that word round her, so for her, I could never give her the book to read. My kids have read it. My boys are 10 and 11 - they think it's great. If they can pick it up and read it - it's such an easy read.

"I put taboo subjects in there - it doesn't matter what culture you're from - it's something people don't want to talk about so where I've got the dynamic of four sisters, I can go anywhere with it. These lives are in your hands, there's something really powerful writing characters like that. Fertility is something so lighthearted and serious at the same time."
