The life I touch for good or ill will touch another life, and that in turn another, until who knows where the trembling stops or in what far place my touch will be felt. - Frederick Buechner
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.
