The author attributes the rise in mental illness among teen girls to them "spending hours each day posting photos of themselves and scrolling through hundreds of carefully edited photos of other girls". As someone who was a teen girl suffering depression and extreme anxiety in the 2010s, the idea rings quite shallow. I can assure you I was not suicidal because ... other girls are pretty? what? ... but because of narcissistic controlling hyperreligious parents fucking me up mentally and withdrawing into a smaller and smaller fringe bubble, cutting me off from normal people and normal life. I think the main problem destroying people's mental health is social atomization/isolation/polarization/decay, and social media does have a role to play in that, but is not the problem in and of itself.
