Also from the article - "The rate of major depressive episodes among U.S. adolescents increased by more than 52 percent between 2005 and 2017." Unless we're suggesting that Facebook was popular enough right at the start to change teen moods (I think it was still limited to colleges at this time?) I feel like there's more layers to this. I'm not saying social media isn't a problem, but I wonder if it's also just a lot of "growing up post 9/11" baggage?
