You’re a Miranda!
"If you stop, it stops. So you don't stop."
"So, it's just you?" Yep. Just you. Every form, every audit, every 2am boiler alarm: just you. You once nearly choked on dinner alone at your desk and your first thought was that the grant report would be late. You don't ask for help. You write the emergency numbers on your arm in Sharpie and drive yourself. You tried taking one day off once and spent it missing NPR, payroll, and the specific hum of your own printer.
Your strength: You are relentlessly, terrifyingly capable. This organization would survive an apocalypse on your spreadsheets alone. People say "I don't know how she does it," and the honest answer is: at great personal cost.
Here's what's going on: This one needs saying plainly. The overwork isn't devotion and it isn't a personality trait. It's a structure where one person absorbs every gap, dressed up as commitment to the mission. Somewhere along the way, "we work for the mission" started meaning "my time is worth less." It isn't. You need shared load and rest that's built into the system instead of borrowed against you.
Do this in the next 24 hours: Pick one recurring task and hand it off entirely. Not "get help with." Off your plate, someone else's name on it. It will be done at 80%. An 80% task done by someone else beats a 100% task done by a chronically tired employee.
