PROBLEM: Person1: Nurse , I am sure to die soon . They just don't tell me the truth , I know .
Person2:But I don't think so . No one has ever said a word that you are to die , only yourself . That means you are not willing to die , right ? Actually , you are recovering and what you imagine as your worry is slowing down the treatment . Many cases worse than yours turned out to be hopeful and successful . You must be confident . Your condition is much better physically , but a little bi difficult mentally . The most important thing for you now is cooperation with us .
