My mom is my dad's primary caregiver following his stroke 10 months ago. She refuses to organize or take him to all of the therapies that have been prescribed and recommended by his doctors, because she feels she is doing enough by taking him 3 times per week, and because it would be inconvenient for her to do more. I live far away and am incredibly worried about him. I have set up an Uber account so she wouldn't even have to drive him, but she refuses to organize it, and won't allow me to. What can I do to fix this?
