I left Amazon in June of this year, in a similar-ish position to the author. I didn't have anywhere near that level of problems with the internal tooling[0], my frustrations were more related to seeing poor product prioritization decisions, neglect of tech debt, and repeated inefficiencies and mistakes in org-wide projects. Nonetheless, the feeling choosing to prioritize one's own mental health and recovery really resonates. Good for you, author! Take a break, get back in touch with yourself and what you care about, prioritize your joy, and I wish you all the best of luck in your next project!
