That part makes sense to me, the WHY is where I am curious. Why do people in my age range, and esp. younger seem to be hysterical and dramatic? I think about phrases like "I'm over that/this", "I'm DONE with____", "I'm BLOCKING you"
I think life exposure is a lot more stressful. I wouldn't primarily place it on the fact of global existential crises, because we've always had those. But young people today are far more connected to the crises on a daily or even minute-to-minute level. Back in the day 95% of your life was in your hood, and for the majority of the population that wasn't causing massive stress levels on a daily basis.
Nowadays, young people are constantly worried about Covid, Trump, Ukraine, global warming, rising fascism, rising awareness of sexual assault, police killings of black people, destruction of the Amazon, economic manipulation by the rich, and every other big public issue. The news cycle is 24/7, social media is omnipresent, they can't get away from any of it. It's dominating their thoughts all the time. That's an awful way to grow up. How can any one child carry the weight of the world and constantly have on their heart any bad shyt that happens to any of the 8 billion people on the planet?
Paradoxically, I think to an extent that while our youths are overexposed to the weight of the world, we've also been building them up with less resilience. Since the 1980s or so parents have been afraid to let kids play outside without adults controlling the atmosphere. They've been afraid to let kids just disappear for the day and come back with adventures they discovered on their own. Adults hover a lot more, kids get the chance to work out their own issues a lot less. Kids spend more time indoors, more time in supervised activity, more time in a controlled environment. And the result is that we've got a lot of children growing up and coming to college who don't know how to handle shyt when life doesn't go perfectly and no one is in control.
Finally, I think social media has been a horrible influence. It rewards people who seek attention, catastrophize their issues (which is a DSMV symptom of several disorders), and project their problems onto the outside world. There's no social media reward for "I'll keep this to myself" or "I can handle this on my own", and there's not much of a reward for "I should fix what I can control rather than externalizing my problems onto the outside world." Even when people say those things on social media, the very fact that they're saying them rather than keeping it to themselves shows a need to look for attention and affirmation, and are followed by all sorts of comments that reinforce the exact opposite of the claim.
For me those are the three dominant strands that have led to kids growing up dysfunctionally.
