it's about a girl whos had something happen to her that means she cant let people close to her. and no matter how hard you try "its not fading..." she is trying to convince herself that shes not alone in the chorus. "strangers walking my way, im talking to myself" to me means she feels everyone is a stranger, but is not willing to make them anything more than strangers, because they wont understand her pain. hence the she is "talking to myself" part
