I think the girl he is talking about is his mother possibly. I heard something something might have happened to her and that could be it and if so thats horrible and im very sorry :(. as for the rest of the song and cant make up my mind whether i think the chorus is him talking to God or God talking to him. I can see him there questioning God saying where were you all this time and why did you let this happen to me...and i can also see is as God saying 'I Found You' like this (lost and insecure, lying on the floor, etc..) and where have you been and why did you get so far away from me and wait until your life got so bad to come back to me and ask for me help. i think the second one makes more sense because i am a christian and i believe that we find God, not the other way around but im just trying to look at it both ways. i would love some replies and to hear the others about this! God Bless!!
