Each of these has woken me in the middle of the night to wrestle with at least once:
The inevitable death of people I love. Being seen through. Exposing vulnerabilities and insecurities. Losing everything and winding up homeless and alone. That I secretly don't matter. The exposure of my worst aspects. To be seen as foolish. To be seen as incompetent. My own inevitable decline and death. Pain, both emotional and physical. Loss of love.
