In that first stanza alone I love the imagery of the streetlight like a yolk thick and heavy clinging to everything flowing like honey over the path and it also has an interesting potential double meaning with yoke which is often used a symbol to depict subjection or imprisonment like "under the yoke of a cruel master" which plays into the next stanza as you are almost a prisoner stuck in place frozen in amber under the yoke of the yolk of light and your own indecaision follows throughout the entire poem as you become a prisoner of your own loss and inability to take that next step and your own frustration at knowing the path but being unable to walk it, yet also being freed by simply making a choice, right, or wrong making that light then feel just a little more hopeful even if the wounds still bleed.
And it may not be intended but because of the title I see a parallel between being under the sodium light and being under the limelight , it makes me feel like you're giving a grave soliloquy under a phosphorescent stage light , while we the audience are watching you yourself watch the one you've lost it makes the tone of isolation much stronger when I read it that way
I Absolutely love it
