These days, I think a lot of kids have anxiety and depression from growing up in a volatile time globally, as well as spending so much time on social media and gaming. There is more pressure on them than ever to succeed academically, and the dizzying pace of information can only have a fragmenting effect on their developing minds. Furthermore, add in those with shitty parents or siblings or whatever and the normal difficulties, stresses, and pressures of growing up, and it's clear to see why young people are having a hard time.
I fall into this category even though I'm in my 30s. Had a very sheltered/emotionally abusive upbringing, and nobody who should have clued into the fact that I needed a heavy dose of reality. I thought things would be a cinch once I got my independence. Growing up in the 90s mainly, I lived a fantasy life without realistic parenting-rather, out of touch boomers (one very narcissistic alcoholic and the other passive enabler) led to my demise. I crashed and burned immediately upon turning 18, and it's been a massive uphill battle ever since. The number of bad decisions I've made is too many to count, and I do attribute a lot of that to thinking "things are gonna work out just fine anyway". Cue severe mental illness with an onset over a decade in the making, and I certainly got my dose of reality all right. I've gone through more suffering than anyone I personally know and been through hell and back with psychotic delusions and hallucinations, followed by multiple years long deep, suicidal depressions. The things I've seen and been through in these experiences alone are shocking and saddening, from doctors to colleagues to the homeless to friends and family...it's all been dark and depressing. I grew up escaping on the developing internet and through video games-which was a nice time to be alive-but the real world crushed me due to both my genetics and environmental upbringing. I certainly "get" things now about the world, but it's far, far too late.
Personally, I see mental illness and suicide rates growing dramatically over the future, though I won't be around to see it. I do not see society suddenly becoming more accommodating and understanding; it's already hyper-competitive and people cling to whatever scraps of success they can get. Just looking at the contrast between vanilla "mental health awareness" and what it's *actually* like for people in communities like SS...at least we talk about things now, but for people in really shit situations...good luck. It seems like things are moving much more in the direction of every person for themself, both socially and economically. Lots of individuals, groups, and companies do lip service to inclusivity and acceptance, yet we have insane numbers around the world in crisis at any given moment.
Fundamentally, it's just an overpopulated and incredibly complex world, and there is not a lot of room for error anymore. I'm not gonna be one of those "wrong generation" types, but the world I expected growing up is not the world I entered and live in-partially my fault for bad decision-making, but even moreso because of the parenting I received (or didn't!). For better or for worse, the world has told me I'm not welcome in it, quite succinctly...and though it may not be so dramatic for others, I think plenty of others end up getting the painful picture like I did, soon enough. Once I started having a really hard time, I was abandoned progressively more as time went on-but it started at home as a kid. "Hell is other people".
A bit rambling, but I hope that serves as somewhat of an answer.
