Depressive (masochistic) personality:

Definition

Persons with depressive personality disorder are chronically morose, worried, and self-conscious. Their pessimistic outlook impairs their initiative and disheartens persons who spend much time with them. To them, self-satisfaction is undeserved and sinful. They unconsciously believe their suffering is a badge of merit needed to earn the love or admiration of others. This personality disorder is considered a temperament that usually does not result in social dysfunction.
