The psychological term for being paranoid all the time is "paranoid personality disorder" (PPD). Paranoid personality disorder is a type of personality disorder characterized by a pervasive pattern of distrust and suspicion of others. People with this disorder often believe that others are constantly trying to deceive, harm, or exploit them, even in the absence of concrete evidence to support these beliefs.
Individuals with paranoid personality disorder tend to interpret the actions and motives of others as malevolent, and they may have difficulty forming close relationships due to their mistrust. This condition can significantly impact various aspects of a person's life, including their social interactions and ability to function effectively in different settings.
It is essential to note that occasional feelings of paranoia can be a part of the normal human experience, especially in stressful or threatening situations. However, when such feelings become persistent, unwarranted, and significantly impair daily functioning, it may be indicative of paranoid personality disorder or another related mental health issue. As always, a formal diagnosis can only be made by a qualified mental health professional after a comprehensive evaluation.
