"characterized by defensiveness and hypersensitivity....
"Narcissistic vulnerability" entails (on a conscious level) "helplessness, emptiness, low self-esteem, and shame, which can be expressed in the behavior as being socially avoidant in situations where their self-presentation is not possible so they withdraw, or the approval they need/expect is not being met."
