I think this song is talking about how you don't want to accept that something you loved is gone.

First verse-I took their smiles and I made them mine.
She has been pretending to be happy, acting like nothing is wrong. But now she knows that the person she was pretending to be isn't her (and now I see what I really am, a thief, a whore, and a liar)
Next, she has been seeing the thing she loved is gone. (I see you there, Farther away) She sometimes wakes up in the middle of the night, and is sure her loved one is there. But she awakes to find nothing there. She is trying to forget this loved one, but she can't be there without her loved one. She keeps trying to reach her loved one, but each time he's farther away from her.
