Game of Thrones star Sophie Turner slammed British TV personality Piers Morgan after he criticized celebs who chose to talk about mental illness.

The back-and-forth began when actress Beverley Callard was quoted as saying she thinks stars try to make mental struggles “fasionable.” Morgan concurred, tweeting: “She’ll be hammered for saying this, but it’s 100% true.”

Turner responded, tweeting that talking about mental illness is important, especially considering it “affects 1 in 4 people in UK per year.”

Social media users applauded Turner. “Ugh. People who think there is no problem is the problem,” said Twitter user @DrunaRawr. “No one WANTS a mental health issue, but those who suffer absolutely do not want others to feel isolated. The mental health system in the US is a JOKE!! Thank you for being our voice @SophieT !!”
