Your need to rest, to escape, to start over, to dissolve--even temporarily--is nothing more than a demonstration of self-care. We value exhaustion in our culture, we value skin-of-our-teeth, edge-of-our-seats desperate and determined flying by night.
I think we all realize that this is no formula for reaching old age at all, much less gracefully, much less reaching health and sanity in whatever age we happen to be residing. No. You do what you must do so that you can attend the real work of this life with music, with grace, with something approaching joy.
