Protagonist's Emotional State through Setting

In the following excerpt from a short story, the setting profoundly impacts the protagonist’s state of mind:

"She stood on the edge of the cliff, the wind whipping her hair back. Below, the ocean churned violently, waves crashing against the rocks, sending sprays of saltwater into the air. The sky was a gray mass threatening rain, mirroring her tumultuous thoughts. She felt small and insignificant, lost in the vastness of the landscape, as if the world were imploding around her."
