Anyways, I think you are spot on at describing the way it really is for a young woman, whatever her reason may be. It is easier to make a decision when you're not actually there at the doctor's office. But once your name is up, it seems as if life flashes you by and there is hesitancy, alarm, doubt, maybe even wanting of changing your mind.
I like the way you write "She clutches my hand and says 'I'm sure'", making it seem like she's not sure at all. And then the feeling becomes even stronger by the end. I sincerely sympathize with the protagonist.
