Meaning of "Heart Attack" by Wavves

The lyrics of "Heart Attack" seem to delve into the experience of being in a toxic or one-sided relationship. The repetition of "I'll do anything you want me to, do" and "We could do anything you wanted to, do" suggests a sense of desperation and a willingness to please the other person, even at the expense of one's own well-being. The reference to a heart attack could symbolize the overwhelming stress and anxiety that often come with such relationships, where one feels like they are constantly on edge, waiting for something disastrous to happen. The line "My thoughts get lost, the air is putrid" may indicate a sense of suffocation and unease in the relationship. Overall, the song portrays a feeling of helplessness, being trapped, and the fear of impending disaster.
