Nina Langton had no right to be depressed. At least, that’s how she saw it.
She had a great group of friends, lived in a prosperous neighborhood, and was close with her parents. Like most 16-year-olds at her Connecticut high school, Nina spent much of her free time on her smartphone. But unlike many of her classmates, she was never “targeted” on social media—her word for the bullying and criticism that took place daily on sites like Snapchat. “Part of what made my depression so difficult was that I didn’t understand why I was feeling so sad,” she says.
