We have some good theories, but almost nothing is definitive. Good counselors and doctors will tell you this. Pharmaceutical and insurance companies would like us to believe there are objective diagnoses, easy answers, and successful treatments. Sometimes there are, but not usually. We put unrealistic expectations on these fields when we demand objective answers for something so deeply subjective and personal, something that can have genetic, biological, interpersonal, spiritual, economic, and circumstantial causes all at the same time.
