existential despair

Existential despair is a profound hopelessness arising from confrontation with life's fundamental conditions—mortality, meaninglessness, isolation, or the burden of freedom.

Unlike ordinary sadness tied to specific losses, existential despair stems from recognizing that existence itself offers no inherent purpose or guarantees: After his diagnosis, he fell into existential despair, questioning whether anything he'd built mattered.

The term draws from existentialist philosophy, where such despair may be a stage toward authentic living or a permanent condition.
