"Goodbye" Is About Saying Goodbye To A Part Of Oneself The "girl That I Was" And The "girl That You Lost". The Song Acknowledges The Struggle Of Accepting The Mistakes Made But Also The Need To Let Go And Move On. The Pre-Chorus Mentions All The Energy And Love That Had Been Poured Into Others But Not Into Herself And She No Longer Wants To Be That Person. The Chorus Is The Goodbye To This Girl A Goodbye That Is Made With Peace And Without Regrets. The Bridge Speaks Of Current And Future Pain But Also Of The Love And Memories That Remain Regardless Of What May Happen. The Outro "My Friend Friend" Is A Reminder Of The Growing And Healing Needed For A Better Future.
