The psychological term for being paranoid all the time is "paranoid personality disorder" (PPD). Paranoid personality disorder is a mental health condition characterized by a pervasive distrust and suspiciousness of others, even when there is no apparent reason for these beliefs. Individuals with PPD tend to interpret the actions and motives of others as malevolent or harmful, and they may be hypervigilant in anticipating betrayal or deceit.
It's essential to note that occasional feelings of paranoia can be a normal response to stress or certain situations, but when these feelings are chronic, severe, and interfere significantly with a person's daily life, it may be a sign of a more significant issue like paranoid personality disorder. If you or someone you know is experiencing persistent paranoid thoughts and it is affecting their well-being, it's essential to seek professional help from a mental health provider for an accurate diagnosis and appropriate support or treatment.
