Why is Taylor so depressed in the bean trees?

In "The Bean Trees" by Barbara Kingsolver, Taylor Greer experiences depression largely due to her feelings of isolation and the pressures of taking on new responsibilities, particularly after becoming a guardian to an abandoned Native American child, Turtle. The challenges of motherhood, along with her struggles to find her place in a world that often feels overwhelming, contribute to her emotional turmoil. Additionally, Taylor grApples with her past and the fear of failing in her new role, which adds to her sense of despair. Ultimately, her journey reflects the broader themes of resilience and the search for belonging.
