What is the narrator's turning point in the novel, Whereabouts?

Toward the end of the novel, the narrator visits the location and reconciles some of her feelings about her father, coming to the conclusion that much of her need for solitude and difficulty in forming lasting relationships stems from his standoffishness and reclusiveness. The crypt symbolically represents the ultimate form of solitude, whereby one is permanently alone. Therefore her visit to the crypt represents a turning point in the novel wherein she realizes she must strive to form relationships or else end up like her father.
