Answer:
Burnout is a physiological condition in which the patient is emotionally and physically exhausted and can achieve little or nothing. It mainly consists of three symptoms: extreme fatigue, aversion to work or the people with whom one works, and a lower self-image of one's own competences.
Too much stress at work and in the personal aspects of life would be causes of a burnout. A sensitive personality with an above-average sense of responsibility and a tendency towards perfectionism would be risk factors.
