While I am happy to see that

While I am happy to see that your treatment went well, but what the Doc is suggesting is that CBT is not for everyone, and that more "classical" treatments are still perfectly good options. And disregarding research studies just because of your experience alone is not what's best for psychological treatment and research. Moreover, just because a treatment is short and quick does not make it the best. Psychodynamic therapy or psychoanalysis can have positive effects on the personality of the patient as a whole rather than just the symptom removal alone. Finally, like all forms of treatment, it has its weaknesses. Those in an overt state of psychosis don't respond well to CBT.
