Saturdays singer Frankie Sandford has opened up about her battle with depression, admitting that before she sought treatment she felt “worthless” and “ugly”.

“Since childhood I’ve been an over-thinker,” says Frankie. “I used to make myself sick with worry. I’d always have stomach aches and breathing problems. I felt that I was worthless, that I was ugly, that I didn’t deserve anything,” she tells Glamour in a new interview.

When Frankie eventually decided that she needed professional, she admits to worrying about how other patients would perceive her,

“I was so nervous, because I was "Frankie from The Saturdays". I didn't know if people would be horrible to me and say: ‘You're in a successful girl band, you've got this great boyfriend, he's got loads of money.’But nobody judged me. Nobody thought I was weird.”

Spiral of negative thinking

The 23-year-old star – who six months ago took time off from The Saturdays – has also revealed that her illness affected her relationship with boyfriend Wayne Bridge.

“One night, I got upset because Wayne hadn't bought the right yoghurts. I managed to convince myself he didn't know me at all.

“It set off this spiral of negative thinking – that if I disappeared, it wouldn’t matter to anyone. In fact, it would make everybody’s life easier. I felt that I was worthless, that I was ugly, that I didn’t deserve anything.”

I feel like me again now

Frankie – who decided to share her experience as part of Glamour’s ‘Hey, It’s Ok’ campaign in conjunction with the mental health charity Mind – now says that she now thankfully feels better,

“I did lose myself,” she says. “But I feel like me again now. But I try not to put pressure on myself – it’s unrealistic, no one is 100 per cent happy all of the time.”

We’re just happy to hear that Frankie has made a recovery, and that she’s not putting so much pressure on herself.
