The remix of "Goodbye" by Itsnotyo_boiiii takes snippets of various lyrics from different songs and combines them to create a new interpretation. While it's important to note that the remix may not have a cohesive narrative or message, we can still analyze the meaning behind some of the lyrics that are featured.

The intro, "Please, please, Don't leave me be," expresses a sense of desperation and a plea for someone not to abandon the speaker. This could indicate a fear of being alone or a desire for emotional support and connection.

The line, "Take me to the rooftop, Told you not to worry," might suggest a desire to escape from reality and find solace in a moment away from the pressures of life. It could also imply a warning to someone close to the speaker not to be concerned about them, perhaps indicating a self-destructive nature.

The phrase, "I'm no good for you," reflects a sense of self-awareness and acknowledgment that the speaker may be a negative influence or bring harm to someone else. This could indicate a struggle with guilt or a belief that they are unable to offer anything positive in a relationship.

The mention of feeling unwell in the line, "Baby, I don't feel so good," suggests emotional or mental distress. It could imply a sense of sadness, hopelessness, or even physical illness. This line adds a layer of vulnerability to the speaker's emotional state.

Referencing the line "And all the good girls go to Hell" from Billie Eilish's song, the remix touches on themes of rebellion and challenging societal expectations. It could convey a sense of being misunderstood or going against the norm, which could contribute to the speaker's feelings of being the "bad guy."

Overall, the remix incorporates a mix of emotions, including desperation, self-awareness, vulnerability, and rebellion, to create an intense and complex portrayal of the speaker's state of mind.
