In this quote, Miriam Toews likens depression to a dark house without windows, implying that it is a place of isolation where one cannot see or connect with others beyond their own reflection. The house symbolizes the mind trapped in sadness and despair, making it difficult to reach out or gain perspective outside of oneself.

The mirrors represent how a person experiencing depression only faces their own image, emphasizing self-absorption and introspection that can hinder understanding or empathy toward others. This metaphor highlights the isolating and introspective nature of depression, suggesting that it blinds individuals from the outside world and genuine human connection.
