What to do when the person does not deal with it?

Hi Dr, good morning! My father is 70 years old and he is diabetic, and he takes insulin every morning, but he refused to take it yesterday, and he is sobbing, burping, and not thinking about eating right, what he thinks he is, and what he advises me to do , because he is very crude, strong and ignorant, soon he only does what he wants and he thinks it is correct, I tried to take him to the hospital, but he said that even he is not dead.
Expert answer:

The patient and his family (unless under judicial conditions) have full right and freedom to choose what to do with their own health and it is up to physicians and others to respect this right, even if this may lead to an unfortunate outcome. No one can force your father to do something he does not want, no matter how difficult it is for you family to watch this situation, we know where it will come from, you have to respect his will.
