I wrote a book called “Eating Glass” about the grueling emotional and psychological experience of presiding over a prolonged startup failure, coping with the aftermath, and finding my way back to health and growth.
I wrote the book I wished I’d had available to me, as I believe these experiences are common among entrepreneurs and high achievers. My “Show HN” was immediately lost downstream but I have given out free digital copies on a few occasions in response to folks posting here about similar struggles.
I have links and a lot of free excerpts at https://markdjacobsen.com/eating-glass/
