Actually in psychology there is exactly that distiction between two types of stress: Eustress and Distress. The first, eustress is what you could call 'positive' stress, stress that you can cope with and that induces change, growth, and learned experience. The second, Distress is stress that is too much for you to cope with either in type or intensity, it's the type of stress that would likely trigger a physical flight or fight response and all the health issues associated. The distinction is tenous but the point is stress is sort of needed, just has to be in a dosage that you at an individual level can cope with.
