You're really not alone in this. Nature exposure has helped a lot since the industrial revolution as far as any mental health concerns go. A return to the old world, full of trees and brush is still there for all of us.

This is what people mean by 'Go touch grass'. They're not being literal but it's a few simple words that just say go experience primitive roots for a few hours and come back to the artificial world we've created for ourselves.

I used to reject the particular notion until I went outside and depending on where you live, you might experience verbally hostile people if you're alone. Which goes to show there are others feeling far worse if they're being verbally hostile to random people.

The more I read HN symptoms the more I point to trees.
