The 23-year-old became a popular name after starring as Sansa Stark in the show "Game Of Thrones".
While talking to The Sunday Times, the newly wed opened up about her mental health and how she managed to over come it. "Everyone's metabolism slows down at 17, 18 and then that's documented. My skin and everything. People commenting on it. I was too aware of my body at a young age. And it just kind of took over my mind, it was all I would think about. Calorie counting, everything. Oh, I'll just eat nuts today," she said.
She confessed that she started to get medical help after not having period for a year, reports metro.co.uk. "I've learnt that I have to turn down jobs if I need to lose weight for them because it's not good for my mental health at all,' she admitted.
"You feel so much pressure to say yes, but I've learnt that I have to put my mental health first, beyond anything, otherwise I'm screwed and then I might actually end up in rehab."
The star revealed she was saved by her husband Joe Jonas during the time she was mentally unwell as he helped Turner to love herself.
