It suggests that the fear consumes the narrator's thoughts and emotions. The lyrics also hint at a troubled relationship or perhaps unrequited love. The line "Livin' and beaten' but I can't go near" implies that the narrator may be experiencing difficulties or hardships, yet still longs to be close to this person. The repetition of the line "One thing to do, gonna go missin' if I can't see you" further emphasizes the narrator's desperation and dependence on this individual. Overall, "Greatest Fear" portrays a deep emotional attachment to someone, where their presence becomes essential for the narrator's well-being. It explores the fear of losing that connection and the anxiety that accompanies the prospect of living without them.
