Many people in here arguing things "have never been better". It's true to an extent; things are pretty good in terms of poverty, liberties or world peace (for now). It's not great, it's never been great, but it's a decent bit better than it's been in the past. Overall.
We are, however, in an era of unstability and unrest, where it feels like things are constantly on the cusp of changing for the worse (and in some cases, are indeed already changing for the worse, like abortion or LGBT rights in the US, for example). Violence and discrimination are on the rise, global peace is being threatened, democracy is in jeopardy (not just in the US mind you), the 1% are getting WAY richer way faster than ever... To top it all off, climate change is objectively, unarguably as bad as it's ever been, and it's getting much much worse, much faster than even experts can keep up with. Like, we're headed straight for extinction and we keep accelerating toward it.
You have every right to be worried. Yes, it's easy to forget and take for granted the things we have now that we didn't even a mere 60 years ago, but many of them are very much under attack at the moment. Just because shit maybe hasn't quite yet hit the fan doesn't mean everything is fine.
And to answer your question, I've found some refuge in art, both experiencing and creating it. Reading books, watching movies, playing games, etc, especially those that echo that sentiment of fear and uncertainty for the future (or present). Trying to use all that as inspiration for my own work, I think it'd help to express my feelings this way. I am indeed doing very poorly still though, it's a lot to deal with, on top of my own personal problems.
I've given up personally. I don't know if it's life circumstances or me not being as good at heart as I'd hope, but I've resigned myself and I'm just trying to learn to cope with the loneliness. At some point it's fair to call it quits and start being realistic.
That's just me ranting though, this isn't directed at you, and I wish you the best of luck.
