That is exactly how The Man wants us to feel: so sad that we never try to make things better; so cynical that radical change seems impossible; so alone that we never realize we are in this together!
It's okay to feel your feelings.
So, treat your sadness like a friend. Put your sadness to bed, gently. Tell it that you understand it and care for it, but it needs to rest.
And then: let's get organizing! Let's get moving! The anarchic phenomenological communitarian revolution to make our mutual flourishing possible won't start by itself!
