What does Tayo struggle with upon returning from World War II in Ceremony?

Tayo's primary struggle upon returning from World War II in "Ceremony" revolves around dealing with battle fatigue and trauma. The novel portrays his experiences with post-traumatic stress disorder (PTSD), which manifests through flashbacks, disconnection from reality, and feelings of alienation. Tayo's trauma is not just a personal battle; it also reflects the broader struggles faced by Native American veterans and their disconnection from both their cultural roots and the society they fought for. This difficulty in processing his experiences in the war leads to a sense of isolation and confusion about his identity and purpose, making it a central theme of the narrative. Through his journey, healing from this trauma becomes essential for Tayo, intertwining with the broader themes of cultural identity and the importance of community and tradition in recovery and wholeness.
