The big mental illness crisis of the 21st century is really the same one from the 20th: mass media consumerism. Social media is literally just mass media consumerism in a more efficient, evolved form. It's the car compared to the bicycle: more advanced, with more bad outcomes than before. If you want to cure social media mental illness you'll have to wrestle with the fundamental addiction all humans now have to mass media, which has a symbiotic relationship with consumerism. Since the global economy depends on consumerism, it's not going to be easy to dismantle.
