No, I mean I'm not letting news affect my mood unless it is truly significant. I still check the news (trying to reduce) but not getting worked up about things as much.
I did the same, basically, by quitting Facebook. Technically, I didn't quit it, just deleted the app from my phone. I was a daily poster and habitual feed browser and commenter but I stopped cold-turkey. I was worried that I wouldn't be able to do it but I did and it turned out so much better than expected. Stress level is way down. Way less desire to live up to unrealistic, self-imposed expectations. When I check it from my laptop every few days, it feels incredibly hollow and I usually just close the window after reading a few stories.
One funny habit I retained is taking lots of photos throughout the day--they just stay there in my camera roll now.
