Give Up the Ghost Lyrics Meaning

I believe this song is about someone the narrator has lost (deceased). In this case I believe the person encapsulates a motherly persona, and the narrator is asking that she take on the heart felt problems of anyone, and everyone; incuding himself. She encapsulates someone that always thought of others before herself. Someone with open arms, hence "In your arms". The narrator, and everyone else in the song, takes a child like character and casts even the impossible into her hands (arms), because she can do, in the narrator and your own mind, anything. Finally at the end, and pinnacle of the song, he, and anyone else who has cast their pains upon her, are finally ready to let her go, and with her death, all their troubles. This is represented in "I think I have had my fill (In your arms), and "I think I should give up the ghost". Like a child who has grown, we must release ourselves and become our own person.
