Unwanted Caregiving Advice

QUESTION: "I am my father's caregiver. He lives in my home and requires 24-hour supervision. He needs help preparing meals, bathing, getting to appointments, and managing his finances. It's a tough job, but I don't regret it. What drives me crazy is the comments people make to me. I am frequently told I am doing too much. People flat-out tell me they would never do what I am doing. Some even suggest that I put Dad in a facility for my own health. The truth is I care for him because I want to. What do I say to people who give me their unwanted caregiving advice?" - READER
