How have you been keeping yourself rational and sane?

Just take it day by day and give yourself plenty of time to relax. Treat yourself like going to a fancy restaurant. Go on nature walks. Be active and get some sun light.

Avoiding society, shopping online, creative hobbies, entertaining romantic delusions.

Not engaging with the idiocracy.
Wherever it is.

Politicians have proven themselves worthless.
Economists have proven themselves thoughtless.
Social media is riddled with people expressing views with no connection to reality other than the one playing in their head.
And everyone wants to tell you what to think.

Work and exercise
