How do I cope with a job that never stops?

You hold order in a system that never sleeps, and that skill is real. But a machine that can never fully stop asks something no person can give without cost: constant readiness. Feeling worn down is not failure. It is the honest weight of the work. The pressure will not go away, because the system is built to keep running. What you can change is how much of it you carry when you are off the clock. The trains, the schedule, the next shift exist whether or not you are turning them over in your mind at home. Build one hard edge between work and rest. When your shift ends, mark it somehow, with a walk, a change of clothes, a few slow breaths, and tell yourself the system is someone else's to hold now. You keep order best when you also let yourself fully stop, even if the system never does.
