Social media gets blamed for a lot of ills, but sometimes the results are exaggerated. Here is an interesting quote from The truth about the suspected link between social media and self-harm
While some studies have found a link between social media and suicide, Przybylski’s colleague Amy Orben has noted that the correlation with mental health issues is tiny. In one study, social media use explained only 0.36 per cent of a girl’s depressive symptoms. That figure is so low, it could just be statistical noise.
