　　　　　This article presents the nursing care of a major depressed patient with low self-esteem, hopelessness, self-reproach and disharmonious family, using the concept of Rogers' nursing theory about energy-exchange between human and environment. We applied three homeodynamic principles, resonancy, helicy and integrality, to evaluate the case's life-cycle development, human field and environment field patterns and energy-exchange condition, indentifing the case to be discomforting with living in painful family, present role-playing disturbance, autistic daily living without support from families and friends. Nursing staff and families delivered energy in the nursing practice by using resonancy to adapt the new life, helicy to readjust his life pattern, and integrality to promote harmony between the case and his environment, thus having the case to restore confidence progressively, and sense love and support from families and reach well-being of himself and his environment.
