When i listen to this song, I think of a feeling I've known well throughout my life. Its basically feeling like you're so far gone and such a lost cause that you either don't deserve someone to love you, or once someone does love you, you mess up in one way or another. I've even interpreted it as struggling with mental illness in such a bad way that there will always be a part of you that you supress and keep hidden from anyone trying to get too close to you. Either because you fear they won't understand, or, as most people who struggle with mental illness, you think they'll judge you or leave you for it.
