I had my first major career failure this year and lost a very good job. I was able to land another good job quickly but I’ve been full of doubt and am seriously lacking in confidence ever since. I can’t sleep and have anxiety. The new job has significantly more responsibility and in many ways the pressure that the author describes in rewriting Slack is very similar to what I’m going through. Every time I have a setback at work I am afraid of losing my job. I finally recognized this as burnout and am trying to come back from it but it’s a slow process. I’m trying to exercise more and get enough sleep but the sleep part is still not working all that well.
