Dear Abby: Chronic pain makes babysitting my 3-year-old grandson hard to handle

Dear Abby: I recently retired. I also have fibromyalgia, which leaves me fatigued and in pain, and I never know how I will feel on a given day. My daughter is a single mom of a 3-year-old and asks me to babysit overnight on occasional Saturdays so she can spend the night with her boyfriend.
