It's admittedly not the most optimistic, but here's my take

Let's get the bad news out of the way first: In my opinion at least, odds are things on a a global scale aren't going to truly start to get better until after they reach a breaking point and there's a collapse. Alot of innocent people are gonna get hurt, alot of innocent people are gonna die. To put it lightly: It's gonna suck fuckin' ass. And it might not even happen in our lifetimes.

But despite all that horror, pain and bloodshed that's sadly yet to come, I really do believe in my heart of hearts that after the worst is over and humanity is picking up the pieces of our ruined world, we'll work together and achieve a Star Trek-like utopian future.

It's just that you and me had the bad cosmic luck of being born too early to live in that future ourselves, and that can be an incredibly tough and bitter pill to swallow sometimes. Trust me, I know.

So basically, and I know this is far easier said than done: Just try to accept the big things that are out of your control/ability to change, not overly worry about them and focus on the things you can control and change. Carve out whatever little slice of happiness you can in our shitty world with the people you love, help and care for eachother and hopefully, despite not living in that Star Trek future, you'll still be able to overall have a decent enough life despite it all.
