On screen, all we see as viewers is the fierce, beautiful Sansa Stark in HBO's Game of Thrones, who ends up doing some pretty big things by the show's finale. While Sansa as a character certainly has faced her share of hardships throughout the series, she seems to be a resilient and powerful force. And the actor behind the iconic character, 23-year-old Sophie Turner, has opened up about her personal struggles with mental health and the havoc those issues have caused on her adolescence and young adulthood.

Turner has spoken out about battling depression and an eating disorder. Since she started working on Game of Thrones when she was 13, her adolescence was in the public eye and this publicity became distressing. She recalled to the Sunday Times, "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.'"

Turner also shared that she became so thin she stopped having her period for a full year. At this point, she turned to therapy and now advocates this type of counseling for everyone.

Turner met her now-husband Joe Jonas when she was 20, in the midst of her depression and disorders. He encouraged her to take care of herself first before entering a relationship, and this bluntness helped her see the situation clearly.

"He was, like, 'I can't be with you until you love yourself, I can't see you love me more than you love yourself,'" Turner said. "That was something, him doing that. I think he kind of saved my life, in a way."

Turner's reaction to Jonas' advice was to prioritize her relationship with herself first, and she focused on becoming healthy, both mentally and physically.
