I agree with much of what's posted so far--especially the impact of social media on our youth. There's also the issue of news reporting in general which finds its way into social media. The book Factfulness, by the late Hans Rosling (a retired MD from Sweden and a social democrat) and his son and daughter-in-law gives a good explanation of how news is reported and how people get a grossly incorrect understanding of the human condition on very important issues, such as world health, women's education, the levels of poverty around the world, etc.
In addition, having co-raised two daughters, now almost 33 and 30, and seeing how they and their friends navigated high school and the somewhat early days of social media, I observed that their generation and those younger lived in a world of superlatives. "Awesome" was used in every sentence. If some high level of achievement wasn't reached it seemed like the endeavor was a failure. Everything--vacations, college admissions, first job, etc. had to be the best or it was a disappointment. Sadly, many of my girls' peers were disappointed a lot. And getting back to social media, people report on the highlights of their lives so the disappointment hits home.
