Lyric discussion by Hezzy 

People may believe this song is a reference to his heroin habbit, but I dont think it is.

He's not having an internal debate about taking "one last hit" or kicking the habbit.

He's having an epiphany and he's trying to debate with himselve, whether or not he should kill himself and he recalls to a time in his life that was happy, whilst making a reference to the fact he has little things to go on in the present. When he reflects upon his life, he feels angered that he's not as happy as he used to be and he knows that he has only one real shot at making things work.

Funny that you write that people may believe this song is a reference to heroin use because it's so easy to hear it's not. It is very obvious that it's about a lost love; still loving someone (albeit very obsessively) after a break up but knowing the relationship is over for good, and the song is describing the resulting psychological pain.
