What is significant about how Rhoda appears in Section 7?

Rhoda seems to be continuing her downward spiral of despair and longing as she appears in Section 7. The reader encounters her walking in the Spanish countryside, as she is painfully musing over her belief that she cannot and will not change. Her despair has been exponentially augmented by the death of Percival, leaving her in a state of emotional paralysis that forces the reader to worry about her as her life progresses. At the end of the section, Woolf carefully describes how Rhoda approaches and peers over a cliff, leaving the reader almost expecting her to take a step off.
