Caregiver: that word should weigh more than others on a page, sag it down a bit and wrinkle it, because the simple-sounding job frazzles as it consumes and depletes. Not that it's only gloomy. Caregiving offers many fringe benefits, including the sheer sensory delight of nourishing and grooming, sharing, and playing. There's something uniquely fulfilling about being a lodestar, feeling so deeply needed, and it's fun finding creative ways to gladden a loved one's life. But caregiving does buttonhole you; you're stitched in one place.
