As best as I can recall (I keep blanking on some of this) for a few months post-radiation, I would get up out of bed, get dressed and fed, then go lay down on the couch, getting up only when necessary, until it was time to get undressed and get into bed. And I was already on anti-depressants.

I can't imagine having had to interrupt that routine to run a delivery service for schoolkids, so she's doing better than I likely would have done.

Time and healing from the radiation devastation will take care of this naturally.
