In "Pushing the Limits" by Katie McGarry, the theme of trust is poignantly explored through the protagonist's struggle with vulnerability. The character grapples with deep feelings of abandonment and mental strain, reflecting a profound sense of disconnection from both others and herself. These feelings manifest in her reluctance to place trust in others, rooted in past disappointments.

The metaphor of proving God's existence underscores her internal conflict, suggesting that her emotional state has deteriorated to the point where she feels even divine understanding is absent. This illustrates how lost trust can lead to a profound sense of isolation and confusion, complicating her ability to cope with life’s challenges.
