You are still arguing from the personal to the general. Nobody denies that there are are individual tragedies. However, the question you need to ask is is it worse now than before the Internet and social media and to answer it, you have to take into account everybody, not just the few publicised cases that ended in tragedy.
Yeah but there are terrible cases that don't make the headlines because it's so everyday. How do you think the boys who get shamed over their dick pics feel? What impact do you think that has on them? We know that mental health is declining badly in teenagers and young people and that social media is being blamed. The suicides are the extreme cases we may hear of; what doesn't get publicised are those who self harm, have eating disorders, dysfunctional relationships, drug addictions, sexual dysfunction, domestic violence, porn addiction etc etc etc.
