The repetition of the chorus 'Back to, back to, back to, back to you' emphasizes the constant temptation to fall back into old habits.
The lyrics 'Took a long time, Breaking myself down, Building myself up, Repeating it' depict a phase of self-reflection and rebuilding for the protagonist.
The repeated 'I don't wanna feel fearless' suggests that the protagonist is ready to confront her feelings and relationships, and no longer flee from them.
Overall, the song expresses the ambivalence and inner conflict that one can feel when oscillating between change and holding onto the past.
