These are all signs of paranoid personality disorder (PPD). And, for people with the condition, these feelings and behaviors can be so strong that they interfere with someone’s daily life.

Diagnosis of paranoid personality disorder derives from the diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, text revision (DSM-5-TR).

Paranoid personality disorder may lead to misinterpretation of harmless actions and statements by others. This can cause conflict with all types of relationships, including working with colleagues.
