“ Doctors came to see her singly and in consultation, talked much in French, German, and Latin, blamed one another, and prescribed a great variety of medicines for all the diseases known to them, but the simple idea never occurred to any of them that they could not know the disease Natasha was suffering from, as no disease suffered by a live man can be known, for every living person has his own peculiarities and always has his own peculiar, personal, novel, complicated disease, unknown to medicine. ” - Leo Tolstoy

As a general rule it is usually better to use combined treatments (e.g. psychotherapy plus medication) for symptoms that are more severe and/or more long lasting. With relatively recent moderate levels of symptoms it may well be that psychotherapy and medication are pretty much equally effective at relieving the symptoms. It may still, of course, be important to try to understand why the problem developed and what can be done to reduce the chance of similar difficulties recurring in the future.
