It is very unpleasant to be a Narcissist. He is constantly in and out of dysphorias. The life of the Narcissist can be described as a dysphoric continuum, disturbed by outbursts of acute depression, which last a few days each. The Narcissist does experience Euphoria - but it is usually exogenous and reactive while the dysphoria is endogenous and of dubious etiology. This sorry state can be directly traced to the economy of Narcissistic supply.
Public attention can well be derogatory.
Infamy is as useful as fame, notoriety as good as being renowned. This is the primary source of Narcissistic supply. The important element is not truth but the perception of truth. When the Narcissist loses one or more of these sources he reacts. Dysphoria is an element within a larger emotional reactive pattern.
