Dear Eric: The last four years of my father’s life, I was a near constant caregiver. I visited him daily, did his lawn work, took him to doctor’s appointments, to the barber, occasionally to dinner or a movie. I always took care of his finances and medications. He would call me as many as 10 or 15 times a day about various things or just to talk. After he died about a year ago, I have been overcome with guilt.
