I get what you are saying. Me and my system maintain our best functioning when working too. I rely on work to keep me on an even keel. My system is designed to give the appearance of normal functioning, so when I go to work the work alters automatically switch in and do their jobs.
Once we leave work at the end of the day it is different story. During weekends and vacation time it is a different story. Those are the times I (and functioning) falls apart.
Sometimes it is easier to go with what works best.
