Egoism is also a symptom, an open and running venereal sore on the genitals of the mind.
I have never cared very much about the fine points, because definitions are the most lethal symptom. Is it the moment when we awake stark naked to the realization that all of reality comes down to Larry Flynt i.e. when we first become suicidal. Or, does it even matter that, somehow, you have convinced yourselves of the truth of your own thoughts. Truth and thought are the two most disgusting symptoms, existential puss. Give me none of these matters.
