In the book "Swing Low" by Miriam Toews, the quote suggests that depression might stem from overthinking and constantly questioning things that have no clear answers. This mental cycle of uncertainty and doubt can create emotional exhaustion, making it harder to find peace or clarity.
Such a perspective implies that the act of dwelling on unanswerable questions can lead to feelings of hopelessness or despair, highlighting the importance of acceptance and moving forward rather than getting trapped in endless mental loops.
