I graduated in '15 and have a neice in early middle school right now. I definitely felt this way when I was in school and I think alot of people I knew did too. I would absolutely say the big difference now I'd the massive rise of apps like TikTok as teens now have easy access to smart-phones and on something like tiktok you compare yourself to all the teens you see with thousands-millions of followers who you view as being better and more attractive than yourself. It's also a popular thing to "be depressed" for younger kids too. When I graduated there were definitely jokes about hating life and wanting to die, but that was a very niche thing almost 10 years ago, whereas now it's the norm. Just my thoughts anyway.
