I’ve been struggling with this too, but doing ok mostly. Here’s what works for me:
Spend time with people who make me feel hope instead of despair. It sounds like you know some entitled assholes; don’t spend time with them if they don’t improve you.
Focus on local. What is happening right around me? What can I do to make it better? How am I interacting with my immediate environment?
Focus on what is improving. In many, many ways it’s better now that it has been at any time in human history. Women have more freedom and power now than they ever have. I can learn anything I want to, find out anything I want to, almost instantly. More people are aware of systemic oppression now than ever before, and more people are willing to resist it than ever before.
Pick what to be mad about. There are too many things to be angry about, so I try to pick the ones that I think are the most worth it. For me, they are: wealth accumulation (we’ve come so far, and built such a great civilization, and we let a few rich fuckers loot it. It was a mistake! We tricked ourselves into thinking it was a good idea! But we’re realizing it’s not, and it’s fixable) and systemic racism in the US (Black infants in America being twice as likely to die before they reach a year old than white infants is UNACCEPTABLE). Yeah, there’s an infinite amount of other shitty stuff, but I’m only one person.
Picking and choosing social media/other news sources that don’t send me into a doom spiral. I don’t go on Twitter. I don’t go on Reddit any more. I don’t have Lemmy on my phone (sorry Lemmy, nothing personal, but it’s a bad doomscrolling hole for me). I go on Discord and I read blogs I subscribe to.
I believe that a person can only handle three big things at a time, and everything else needs to take a back seat to those three. You have your business, your family, and your medical debt. Those are your three burdens. When one of them gets light enough, you can take on something else. Gender equality and entitled rich people and identity politics are not your burdens right now. They can take a back burner until other stuff gets better for you.
