That's not surprising to me. The problem is that the entire thing is wholly subjective: based on what the customer "feels" and what the therapist personally  judges as meeting the requirements. No medical tests are needed. How can they? Thoughts and emotions are subjective and ever-changing based on multiple factors (diet, activity, relationships, work, etc). Drugs are the easiest way to "solve" the problem. However they don't solve the problem and usually create new ones.
