In "1Q84" by Haruki Murakami, the protagonist expresses a profound sense of personal struggle and limitation. They convey that managing one's own life and emotional burdens is already overwhelming, leaving little capacity to take on the responsibilities of others. This sentiment highlights a deep sense of isolation and the challenge of dealing with personal loneliness while feeling the strain of life's demands.

This quote reflects a common theme in Murakami's work, where characters often grapple with their inner worlds and external realities. The difficulty of connecting with others and the weight of personal feelings can lead to an introspective existence, emphasizing the importance of self-care and recognizing one's boundaries in the face of emotional challenges.
