I'm in a difficult situation in which me and my boyfriend are the primary caregivers for my grandmother. She has been getting more and more stubborn, and today she decided to drive herself to her doctor's appointment on her own while we were working. She didn't wear her glasses.

She's fine, which I'm grateful for, but I'm not sure what to do. She says she just wanted to go to the beach, but she obviously got lost coming back from the hospital. She says she forgot her glasses, but I know she refuses to wear them. She said the bus she crashed into was parked incorrectly, but there are pictures proving she was the one in the wrong.

I need help on how to tell her she can't drive anymore and how to convince her to wear her glasses. I might also need some support, because I'm feeling completely burnt out.
