I get this. I don't even actively seek that stuff out, but in the interest of staying somewhat informed I follow a lot of news/politics communities here. Negative news obviously sells (in the form of receiving clicks) so a fair majority of my feed is made up of depressing info. I only read one or two actual articles a day, but the summary and/or comments are usually enough to bum me out.
Thankfully the rest of my feed is shitposts, memes, and cute animal pics so it keeps me from actively wanting to die.
