Don’t blame social media for someone’s mental illness
Perhaps make a better point, as written your post seems to imply mental illness is the only issue and social media has no impact on society.
Having raised 3 very successful children my personal experience is that when they grow up they are not equipped to deal with the world directly and all the bad actors who would decisive and abuse them.
This can lead to children doing great harm to themselves, that is not mental illness, that is children not being fully developed and emotionally mature yet.
