What is the fear of existing?

The fear of existing, often referred to as "existential anxiety" or "existential dread," is a profound apprehension regarding one's existence, purpose, and the nature of life itself. It can manifest as a feeling of disconnection or overwhelming uncertainty about one's identity and place in the universe. This fear may stem from grappling with life's inherent limitations, mortality, and the search for meaning. It can lead to feelings of anxiety, depression, or a sense of isolation.
