Existential angst refers to the deep-seated anxiety and unease that arises from the individual's confrontation with the inherent meaninglessness of life, the weight of freedom, and the burden of personal choice. This feeling often reflects a struggle with self-identity, authenticity, and the human condition, leading to a sense of disorientation in a seemingly indifferent universe. In literature and philosophy, this concept resonates deeply with themes of isolation, despair, and the absurdity of existence.
