Burnout.
First level telephone tech support is a high stress, high pressure job even in the most optimal setting. I was taking a mental health day 2-3 days a month.
Ditto for managing a technical documentation repository for Naval Research and Development as a contractor employee. I won’t even talk about working as a contractor employee for the Deputy Chief of Staff—Operations and Plans, Information Support Office, Department of the Army—Pentagon, as an implementation analyst (the requirements for the job was always a moving target. You start on a given project’s requirements, and 24 hours later, you catch hell for not fulfilling the changed requirements for the project, which your superiors never bothered to inform you of said changes.
Add 2 side hustles and a commute of anywhere between 2 and 5 hours one way 5 days a week, and a family that believes in working until you drop dead, then immediately having to get back up and start the entire process, ad infinitum, as well as being forced to work, regardless of illness. (To them, there’s no such thing as burnout. Burnout=fat lazy-assed motherf!cker that doesn’t deserve to eat, let alone live.)
<sarcasm>Burnout, Me????? Nah!</sarcasm>
