ISOLSTION

Isolation... use to be that isolation for mostly was a senior issue. Retirement... where basically almost half our social interaction is eliminated. That leaves family and friends that are busy day to day with their lives... leaving less time for you. The older you get the more friends past away so now there's even less interaction. Plus the desire to make new friends deminishes when you get older... seems to be human nature. Less active physically, staying home more, and the isolation compounds itself. 
NOW, add to this the Covid pandemic... going places is almost nonexistant. Social interaction is extremely limited both by government guidelines and the personal fear of infection, thus the self imposed physical isolation. 
ADD to this the issues associated with social media like Facebook. Flooded with social controversy on politics, prejudice, racism, black lives matter, protests, demonstrations, riots, destruction, and all basically angry, mean, and ulgy... all distasteful and after 4 years of it your face everyday. Too many people promote the controversy, while others are put off by it, and Facebook is no longer a place to socially interact with friends. 
FUEL to the fire, the news media only adds to social contension. Indirectly promoting more social division over a wide range to controversial issues.

AND while everyone is offended by seemingly everything... no one can agree on anything... and its all ugly.

SO... There you have it... The perfect storm for ultimate personal isolation. Physically and more importantly emotionally isolated.

Lots of time to think about it all... everything.
