Any psychological disorder is treatment-worthy iff the patient suffers from it. So not just "you were diagnosed", but "you were diagnosed, have problems caused by it, suffer from those problems, and want relief". So yes to both, treatment can be intended to fix a problem that a patient suffers from that is just related to his perception of things. But it can also be intended to support your interactions with a hostile environment that you suffer from.
