Questions on Sartre, Feminism, and Freedom

1. For Sartre, how does the belief that "existence precedes essence" imply that our choices create standards for all human beings?
2. Why must authentic existence be filled with feelings of anguish (angst), abandonment, and despair?
3. How is existentialism not pessimistic?
4. From a feminist perspective, how might women who think they choose freely not really be autonomous?
5. How can developing self-awareness increase your freedom (particularly regarding how you respond to events in your life)?
