In addition to diet, and you have admitted that one (and it is sooooo important to still eat well, however tired you are), I think or I am questioning one more and that's you ability to turn off the work button when you walk out of the hossie.....that's important too. Continual worry leads to stress and poor sleep....and, do you know what, things will probably continue on without you, maybe in a muddled fashion but those patients will get their support. So find your off switch, may be some breathing or quasi-meditation, or whatever before you go home.....
