My girlfriend is mad at me for not going to the emergency room with her, what should I do?

My girlfriend cut her finger with a bottle of wine she was opening. It was really bad. I wanted to take her to the emergency room in an Uber but she wanted me to drive her, I don’t have a drivers license and I can’t drive. I told her I can’t drive but she said I should drive her because it was an emergency. I told her I can’t drive or I would take her. She said I was making excuses up. I walked out the back door and hailed an Uber to take us to the emergency room. I paid for the Uber to and from the emergency room and she still was mad at me. What should I do?
