Angst

Angst means fear or anxiety... Where animals are guided solely by instinct, said Kierkegaard, human beings enjoy a freedom of choice that we find both appealing and terrifying.[5][6] It is the anxiety of understanding of being free when considering undefined possibilities of one's life and one's power of choice over them... While Kierkegaard's angst referred mainly to ambiguous feelings about moral freedom within a religious personal belief system, later existentialists discussed conflicts of personal principles, cultural norms, and existential despair. https://en.wikipedia.org/wiki/Angst
