22 year old Turner branded the "Good Morning Britain" presenter a "tw**" after he re-posted an article in which "Coronation Street" star Beverly Callard voiced concern over celebrities apparently trying to make mental health problems "fashionable".
Callard has spoken candidly about her depression in the past and in the interview makes the argument that some celebrities might just be talking about mental illness because it's trendy, not because it is something they actually experience.
The 22-year-old actress wrote: 'Or maybe they have a platform to speak out about it and help get rid of the stigma of mental illness which affects 1 in 4 people in United Kingdom per year. "They do those with genuine mental illness a great disservice".
Turner, who plays Sansa Stark in GOT, criticised his response by arguing that celebrities can provide a platform for mental health discussion.
Turner noticed his comment and clapped back-hard.
Game of Thrones star Sophie Turner, 22, hit out at the comments saying: 'Celebrities have a platform to speak out about it and help get rid of the stigma of mental illness which affects 1 in 4 people in United Kingdom per year.

La vidéo de l'opération, diffusée par l'un des hommes secourus, a été visionnée plus de 400.000 fois sur les réseaux sociaux. Mais difficile d'atterrir dans cette zone, surtout en plein hiver.
"Or maybe they have a platform to speak out about it and help get rid of the stigma of mental illness which affects one in four people in the United Kingdom per year", she tweeted.
The former Daily Mirror editor wrote: 'Hi Sophie, please don't abuse me like this - it's harmful to my mental health. "But please go ahead and shun them back into silence".
Sophie, who is engaged to pop star Joe Jonas, said there is a stigma attached to mental health and that it is important to "keep this dialogue going" so people who suffer do not "feel so alone". "You're so loved. You are NOT a burden".
Turner slammed the argument and Morgan's agreement by countering that shaming people for talking about mental health is never okay.
One user then demanded: "Maybe @piersmorgan would like to identify for us which celebs are faking mental health problems and say it to their faces on GMB?" You will get through this.
