21st Century Schizoid Man

[…] a tendency towards a solitary or sheltered lifestyle, secretiveness, emotional coldness, and apathy. Affected individuals may simultaneously demonstrate a rich, elaborate and exclusively internal fantasy world. […] trouble establishing personal relationships or expressing their feelings meaningfully […] Their communication with other people may be indifferent and terse at times. Because of their lack of meaningful communication with other people, those who are diagnosed with [Schizoid Personnality Disorder] are not able to develop accurate impressions of how well they get along with others. […] challenged to achieve self-awareness and the ability to assess the impact of their own actions in social situations […] when one is not enriched by injections of interpersonal reality, the self-image becomes increasingly empty and volatilized, which leads the individual to feel unreal […] he/she is only "playing a part," his own personality is not involved […] the person disowns the part which he is playing and thus the schizoid individual seeks to preserve his own personality intact and immune from compromise […] Preoccupation with fantasy and introspection. […] A schizoid may also be attracted to exploitative relationships in which they long to experience significance and recognition by serving a need of the other. […] The schizoid person is so cut off from outer reality as to experience it as dangerous. […] There often goes with it a feeling of being different from other people. […] Loneliness is an inescapable result of schizoid introversion and abolition of external relationships. It reveals itself in the intense longing for friendship and love which repeatedly break through. Loneliness in the midst of a crowd is the experience of the schizoid cut off from affective rapport. […] a dissociative defense, often described by the schizoid patient as "tuning out", "turning off", or as the experience of a separation between the observing and the participating ego. […] reliance on fantasizing activity is often part of the schizoid individual's withdrawal from the world. Fantasy thus becomes a core component of the self in exile […] Fantasy is also a relationship with the world and with others by proxy […] The idea of suicide is a driving force against the person's schizoid defenses. As Klein says: "For some schizoid patients, its presence is like a faint, barely discernible background noise, and rarely reaches a level that breaks into consciousness. For others, it is an ominous presence, an emotional sword of Damocles. In any case, it is an underlying dread that they all experience."
