Why does Creon say I have neither life nor substance in the Exodus?

In the Exodus of "Antigone," Creon expresses that he feels he has neither life nor substance due to the overwhelming consequences of his decisions, particularly the death of his son Haemon and wife Eurydice. His rigid adherence to Law and Order has led to personal tragedy and loss, leaving him in a state of despair and isolation. This statement reflects his realization of the emptiness that comes from his authority and the devastating impact of his choices on his family and his sense of self. Ultimately, it underscores the theme of the personal cost of pride and inflexibility in leadership.
