Williams, who was 13 years old when she was cast as Arya Stark, said there was a period of time where she was sad after becoming overwhelmed by the criticism on social media.

"It gets to a point where you're almost craving something negative, so you can just sit in a hole of sadness," Williams said.

While she has tried to move past what people have said online, Williams, 22, said she still thinks about comments that hurt her.

"I still lie in bed at, like, 11 o'clock at night telling myself all the things I hate about myself," Williams said. "It's just really terrifying that you're ever going to slip back into it. That's still something that I'm really working on, because I think that's really hard. It's really hard to feel sad and not feel completely defeated by it."

"Honestly, I want a normal life," she said. "I don't want any of this crazy, crazy world because it's not worth it."
