Many of these issues don't directly affect your day-to-day life. If only for your mental health, it'd just be better to not focus on the news and instead focus on what you can control. You can control how you interact with and treat other people, you can control your own health (barring certain medical conditions of course), you can control who's worth being in your life and who isn't, and you can (to a certain degree) control your career or work environment.
I don't know, if there's anything you can take away from this, it's for the best to instead try to ignore the negativity of the 24/7 news cycle and instead focus on yourself and what is in your power. Many of these major problems you listed are far beyond the scope of what a single individual is capable of controlling.
