I thought this was an interesting read, although I don't know about osteopathy, and it might be a bit of a catch-all diagnosis, though perhaps still a useful term?
“Soul sickness,” or demoralization, is characterized by feelings of hopelessness and helplessness and a perceived sense of incompetence. This condition typically involves vague, unexplained physical symptoms. Soul sickness can be efficiently diagnosed by asking patients a series of questions about their personal lives. Patients with this condition require a restoration of their morale and hope.
More: Soul Sickness: A Frequently Missed Diagnosis | The Journal of the American Osteopathic Association (June 2010, Vol. 110, 347-349)I have found that the origin of soul sickness is a patient's inability to deal with internal or external stress. The internal stress may be borne of emotional, physical, or sexual abuse. The external stress may arise from insufficient coping skills for dealing with the problems and suffering that life brings almost everyone. Rather than transcending the suffering, patients with soul sickness have “checked out” of life. They no longer feel that they are competent to live productive lives and to meet the expectations of people close to them.
