The song "Just Do It" by Julia Michaels is about a relationship that is on the edge of breaking up. The narrator can sense that her partner wants to tell her something important, but is hesitant to say it. She encourages her partner to be honest and just tell her what they need to say, even if it means breaking up. Throughout the song, Michaels acknowledges that the relationship has been difficult, but she's willing to face the truth rather than continue to avoid the inevitable. She urges her partner to be upfront with their feelings and not to sugarcoat things or let her down gently. She knows it may hurt, but she believes it's better to face the truth head-on than to keep avoiding it. Ultimately, the song is about the importance of honesty and communication in relationships. Michaels demonstrates the courage to face the truth, even if it means the end of a relationship. She also shows a willingness to move on and eventually find happiness, even if it takes time to heal.
