No. If I had this level of anxiety, I would disconnect from news and online media for a little while to take a walk in the forest to clear my mind and calm down.
To call the headline "US threatens to invade Greenland" unprecedented would be an understatement. You only need to see it once to be justifiably anxious.
I'm seeing these messages in the real world. Adverts on the side of buses are telling me to enlist in greater frequency, and job sites have positions in the Royal Army pinned above everything else.
The only difference is scale, and with the increasing flood of bot users and throwaway alt accounts, that's starting to matter less and less.
Whist there is often plenty of crossover (think car enthusiast forums), I'd hardly call a technical discussion site 'social media'.
