Meaning of "All In My Head" by Missy Higgins

The lyrics of "All In My Head" explore the theme of self-doubt, insecurity, and the power of the mind to create illusions that seem real. The narrator's initial belief that their loved one had left them reflects a fear of abandonment and a lack of confidence in their relationship. The constant search for their partner symbolizes their desperate attempt to find validation and love outside themselves, only to realize that true love and acceptance come from within. The discovery that their loved one was always present in their heart represents the idea that happiness and fulfillment do not depend on external circumstances but on inner peace and self-love. The song encourages listeners to confront their fears and insecurities, challenging them to look within themselves for the love and acceptance they seek externally.
