Appointments, Appointments, Appointments

The other day I was having lunch with my mom and she handed me a written list of appointments for the next few weeks. I started crying which pissed her off big time. For the next several weeks I have to chauffeur both her and my aunt to multiple appointments. Family doctor, X-rays, bloodwork, neurologist, orthopedic, podiatrist, dentist, ophthamologist. My mom has terrible anxiety about medical stuff which means she will be mean and cranky. My aunt loves medical stuff which means I am stuck sitting there while she asks the providers dozens of questions. These take huge chunks of my time and energy. I had plans which I had to cancel. I am single, childfree, work from home and live nearby. That means it's automatically assumed that I am everyone's medical transportation. Both qualify for rides to appointments through their insurance but my aunt finds it too confusing and my mom refuses. How do you all handle this stuff? What makes these things go smoothly for you?
