What do you think of a DNR order/ having the right to die argument?

I’ve had a DNR order since I was 18, my doctor (medical) want’s me to rethink having one in light of my condition(I think the real reason is she is prolife)
(Do Not Resuscitate)

I don’t think I’m going to change it because she doesn’t like it. I’m just wondering what’s your opinion on DNR orders.
(I am in no way suicidal or anything like that)
