I've done something similar. I have stopped watching the mainstream national news networks, namely ABC World News and similar programs. I watched these for a little over a year and after awhile you realize just how little informative news they have to offer.
Take ABC World News for instance, they throw the big headlines in the beginning, which you already know if you've checked any other news site/app. Then, they have these stories on a major car accident or one house somewhere catching on fire and somehow that merits it being on the national news. I obviously have some amount of sympathy for what these people go through, but the name of the program is ABC World News, and yet, there are never any stories about anything outside the US. And don't even get me started about the amount of commercials they throw in.
For sometime I was contemplating about not keeping up with the news for similar reasons that the author stated; certain stories may not interest me and the inevitable realization that there isn't anything I can do about it and making you feel depressed. I found, however, that I like staying informed on what is going on, not only in my local area and the US, but also international affairs. I try to limit my intake of mainstream news through my local paper, BBC World news, and their app; that's it. It doesn't take a lot of my time (maybe 45 minutes in total), I get to be informed on important topics, and see it as a productive way to take a break from school/work.
