In "Redeeming Love" by Francine Rivers, the protagonist struggles with overwhelming sorrow and negative thoughts that consume her completely. This internal turmoil has such a powerful grip on her that it obstructs her ability to perceive the world around her, including the people who care for her. Her focus is so inward that she loses sight of the connections that could potentially offer her salvation and healing.

Her emotional state creates a barrier that isolates her from love and support. This blindness, fueled by her anguish, prevents her from recognizing the presence of someone who could be pivotal in her journey towards redemption. The line captures the profound impact of her misery, illustrating how it blinds her from experiencing the very love she desperately needs.
