Sophie Turner, who was just 13 years old when she was cast as Sansa Stark, has now opened up about how she experienced depression four years into filming.

“It’s weird. I say I wasn’t very depressed when I was younger, but I used to think about suicide a lot when I was younger. I don’t know why though,” she said in a Phil in the Blanks podcast interview with Dr. Phil this week. “Maybe it’s just a weird fascination I used to have, but yeah, I used to think about it. I don’t think I ever would have gone through with it. I don’t know.”

Explaining how social media was a big part of the problem, with people criticising how she looked on-screen, Turner explained: “People used to say, ‘Damn, Sansa gained 10 lbs’ or ‘Damn, Sansa needs to lose 10 lbs or, ‘Sansa got fat.’ It was just a lot of weight comments, or I would have spotty skin, because I was a teenager, and that’s normal, and I used to get a lot of comments about my skin and my weight and how I wasn’t a good actress.”
