I don't think the people in power realize how detrimental it can be to a way a girl looks at herself if she flips through a magazine and only sees one type of woman.

It has to be something people prioritize - it should be the number-one priority: representing all types of beauty, all types of shapes and sizes.

Like anyone else, I can fall into these massive Instagram holes and start comparing myself to other people.

Without social media, I wouldn't have young girls messaging me from Australia or Mexico City or the Midlands, but I do wonder if I'd be on it if it wasn't part of my job.

2014 was a terrible year for me. I got a lot of help from psychiatrists, doctors, and my family, but also from group therapy. I met people from so many different backgrounds, and we were all able to relate to each other. It felt like a real community, and I stole that concept for Gurls Talk.

I've always been obsessed with fashion.

Marc Jacobs Beauty is really exciting for me; when I was at school, I would always struggle to find make-up that suited my skin tone, and I certainly wouldn't find anything from a luxury brand. I'm glad that girls don't have that problem anymore.

In the digital age, there are a million and one ways to find out what someone you fancy is doing - but remember, they can see when you're watching their Instagram stories. If you fall deep into a hole of snooping, resist flicking through the digital diaries of their exes, or at least learn to cover your tracks.

Women and girls inspire me. They drive me.

I always believed that I had to pretend to be happy. But what I've learned is that it doesn't matter what race or class or demographic you come from. I truly believe that sadness is relative.
