how do I make my feed less depress
That's the interesting part of the "old internet", you curate your own feed.
Fediverse,Technology, and Privacy are chock full of all the news, and right now, there's a lot of negative going around.
Start by noticing who's posting in those forums and blocking the ones that are generally negative. We have a lot of bot posting that lays one way or the other. There's a Monday morning US time bot that just floods with the most depressing stuff. If you can't get it to sort out with that, start looking at other technology or news communities. Do the same thing there with blocking doom bots.
You can't pull Artax out of the quicksand, but you can keep him from sinking so fast.
