Paranoia is a common symptom in some personality disorders. It means feeling suspicious or fearful without clear reasons.
Someone dealing with paranoia might believe others are lying to them, watching them, or trying to hurt them—even if there’s no proof. They may start to question the trustworthiness of friends, family, or coworkers. In some cases, this fear can grow so strong that it affects daily life, making it hard to build or keep relationships.
This kind of thinking is often linked to paranoid personality disorder but can appear in other conditions as well.
