Paranoia is a mental health condition characterized by intense and irrational feelings of distrust or suspicion towards others. People experiencing paranoia may believe that others are plotting against them or that they are being watched, even when there is no evidence to support these thoughts. This can lead to significant distress and difficulties in social interactions. Paranoia can occur in various mental health disorders, including schizophrenia and delusional disorder. It can also be a symptom of extreme stress or trauma. Treatment often involves therapy and, in some cases, medication to help manage symptoms and improve overall well-being.
