One part to the five-piece girl band The Saturdays has spoken publicly about her battle with depression and how she was always questioning other people’s opinions of her.

In an interview with Glamour magazine as part of its Hey, It’s Ok campaign, Frankie Sandford admitted her one-month disappearance from the group six months ago was down to her attending hospital.

It was there that the 23-year-old received help for the condition that made her feel like she had lost herself.

The stint in rehab has evidently done her good, however, as she was pictured in a black and white photo looking on top form in a flowery thigh-high bodice and silver necklace.

Frankie told Glamour: “I felt that I was worthless, that I was ugly, that I didn’t deserve anything.

“Every time I spoke to someone, I’d be thinking, ‘they probably think I’m a horrible person. Am I boring them? Do I look ugly?”

Prior to The Saturdays, Frankie Sandford began her career in pop when she joined S Club Juniors in 2001, which was a spin-off ensemble for the successful S Club 7.
