I still haven't joined any other social media platform but damn if masto isn't just the biggest mood destabiliser. On one hand I'm glad it's here so I can get some news but all the news is bad, and there's nothing silly breaking it up. So that's why I don't post much. I scroll a bit and get depressed and then go read about WWII.
I get this. That started happening with me about 4 years ago. It's much too stressful to be bombarded with it constantly. Mute and block key words and create a feed ONLY FOR NEWS/POLITICS if you must, but I've not found that need - I still hear the big, important chunks without even looking for them. Well being is important.
