I agree with the meanings about a relationship, but this song has always hit home almost word for word as a survivor of the effects of five years of severe school bullying. I've said goodbye to who I would have been had this not happened and I wish that person was here every day, it's been a bitter sweet victory learning to love the ghost I see in front of me who is not who I would have been, turning off feelings to not feel the hurts leaves unable to laugh or cry and I can't run or hide from myself, and I'm doing it to myself so I do I keep me from doing it to me? I struggle talking to strangers and come off as odd until I get to know someone better so I'm always left explaining that after it's too late, and it's so bittersweet knowing had I had the ability to be open they would have wanted me. I have tried to explain but can't, so my words have many times been my tears because if you can't explain how you feel to people what are you left with? This song has been healing for me in this setting.
