What does Sartre call the feeling man has upon realizing his responsibility in creating himself and humanity?

In existentialism, anguish is a central idea. Anguish describes the feeling people have when they realize they are meant to create themselves in the world. The concept of anguish is inseparable from the concept of freedom, as it is only through the actualization of our free will that we come to realize our role in the world and fear the possibility of falling short. Anguish is made even more present in a world in which we have no moral absolutes, and therefore, no guidance for our behaviour, for example, in a world without religion.
