Advice on this sort of thing is always contextual.
> So I work, always, because I'm anxious I won't be able to provide for the people around me, my sister won't earn enough to feed her family, my mom won't be able to retire even though her work is killing her, my dad's small business will be ruined if the economy collapses...
This indicates a great attitude. You have a massive sense of personal responsibility, not only over your own life, but of your loved ones. You are what high-performing, generous cultures are made of.
So, perhaps some appropriate advice for you, whose sense of responsibility for everything is overwhelming, is to limit your intake of news. News is becoming more extreme in order to pull attention from digital alternatives. I don't have a good news source to recommend, other than perhaps the Financial Times, that won't exacerbate this trait of yours.
And although some things are tough - we need to get on to sustainable energy and packaging; ongoing wars are still just as nightmarish as they always were - what is considered poor in the 21st century is beyond the dreams of people in the past. Every step of progress, even while it makes some people rich, enhances the lives of millions and (occasionally) billions. The great threat of Facebook is so easy to turn off we could all do it tomorrow by uninstalling it. Compare that to the pre-polio vaccine era, before dentistry and analgesics, the constant real violence of the past, both in war and domestically in pre-police times, the pre-GMO food sources that would've meant a billion starving.
Now a single violent incident can get national attention in some countries, when it was a way of life less than 200 years ago.
So it's not perfect, but if you think things are getting worse, I have to disagree with your news sources. Choose them carefully.
