Caregivers of elderly or disabled loved ones work hard. There’s no getting around the sacrifices of time, energy, private life and often financial wellbeing that caregivers, be it family or professional, often make. However, the rewards that accompany this self-sacrifice can be priceless.With a caregiving history involving decades of caring for multiple loved ones, I know quite a bit about the hard times as well as the blessings of caregiving. Yet, because I’m an eldercare columnist, I receive letters from individuals who have caregiving responsibilities far beyond anything I’ve ever imagined. Many people are providing intensive care for adult children, others for parents or spouses.
