Meaning of "I must be out of my mind" by Royal Republic

The lyrics of "I must be out of my mind" by Royal Republic depict the inner turmoil and confusion that can come with unrequited love or infatuation. The protagonist is caught in a cycle of longing and frustration, unable to resist the allure of someone who doesn't reciprocate their feelings. The repetition of phrases like "She's addictive, I wanna have some more" emphasizes the addictive and destructive nature of this one-sided attraction. The protagonist's self-awareness that they must be out of their mind for continuing to pursue this person adds a layer of melancholy and resignation to the lyrics.
