Stress is a part of everyday work and personal life.
Adding AN to the mix creates more stress, fear of possibilities, grief over the loss of the state of health one once knew, coping with the reactions of self and others, and dealing with any poor outcomes, whether temporary or permanent. We tend to think of stress as something imposed upon us by others or by the world around us. How we talk to ourselves internally. How we depict things. Consequently, one person is optimistic or grateful, and the other is pessimistic or disappointed.
