social alienation

a person's feeling of disconnection and/or isolation from a group – whether friends, family, or wider society – or another individual due to low degree of integration or common values

psychological state and objective process in which the self was a historical and social creation, which becomes alienated from itself via a perceived objective world, but can become de-alienated again when that world is seen as just another aspect of the self-consciousness, which may be achieved by self-sacrifice to the common good
