What metaphors are used in A Rebirth by Faroogh Farrokhzaad?

A metaphor is a figure of speech in which one kind of object or idea is used in place of another to propose a likeness between them. Instead of the speaker stating in the first line that her life is filled with sadness, she states that "her existence is a dark sign." Many other metaphors are used, such as "life / is a long avenue," giving the reader the visual image of life being a road upon which one travels. The speaker also states, "life is a rope / with which a man hangs / himself."
