The trauma of 9/11 makes individuals nostalgic and leaves indelible marks on their psyches. Their personal and political worlds are shattered. Rediscovery is an extravagant problem for them. 9/11 changed their definition of self. The paper analyses changes in their behaviour due to hysteria and its effects on their societal relations. Their distress and anxiety change their healthy relationships with each other into an unhealthy state. Now every individual is disturbed, feeling desperation on mental as well as physical level, having cracking headaches, and so on. This paper tries to study how the mental landscape of individuals changed due to catastrophic events. Mental health disturbance is equal in both Americans and Pakistanis, both the novels show us a story of traumatized people and how they become nostalgic.
