The feeling you are describing for me shows up something like - attuning to the present moment so intently because you are faced truly with any moment now could very well be the last. Trying to consciously face death.
I'm glad you're safe and that you wrote this piece. So powerful. Globally we need to find our way to this space of showing up, helping each other out because truly all of us is in a predicament. Shit is real. Shit is real.
