And that's the kind of thing people think, you know, that if you sign up to be a singer-songwriter you know how to deal with people setting up hate websites, or people being obsessed with you and crying when you touch them, but you don't, and you just have to deal with.

Do what makes you feel good. Remind yourself of what you're good at and make sure you do that.

It's healthy to admit you're not ok. 'It's ok not to be ok' it's brave. But don't let it win. Be sad. Have your moment, your day or week. Then do something about it and be happy. For yourself.

However old you are, however much you love life, however happy you are, how healthy you are, it doesn’t matter. Nothing’s guaranteed. And I think it made me want to take that risk to expose myself as me and not as a version of myself. I don’t become Jessie J. I might put a nicer pair of heels on and a cooler outfit, but I’m still that naughty girl who likes a slice of cheesecake on my day off.

I'm someone who'd never base how happy I am on how much money I have, or how good a restaurant is because of how posh it is.

When I was 10 or 11 people started saying there was something special about my voice. But when I was 15 or 16 is when I really thought my hobby could become my career.

I do my own make-up a lot of the time, and I'm very involved in what I wear.
