This mind that grinds & twists beneath the skin

[GrhmJngL]

...though it's only preference i prefer a cap to start a sentence only when punctuation dictates... As do I, definitely, it was mostly a thing of keeping more formal/old-fashioned conventions because of the form and tone of the poem warranting it.

I agree with all of billy's comments. I'd like to add..there seems to be an abrupt, unexplained shift in point of view in the second half. Who is the narrator? The bride is third person in the first half, and apparently first person in the second half. Maybe I'm wrong, but that's how I am reading it.

Firstly, on top of what I detail here (or maybe more accurately, underneath it), is this whole messy thing of a non-relationship and this dreadfully long and gross story of prolonged simultaneous desire, guilt, dread, anxiety and attachment that would take a couple of thousand words to explain and would bore you all half to death.

Addressing both of you regarding the narrator and the narrative itself, the first three lines are intended to go some way to explain the metaphor, that the narrator's mind is afflicting the body/itself for what it perceives as fault, as a noose destroys the body for what the hangman (as the agent of the societal "big Other") perceives as wrongdoing, the verb "mortify" here supposed to imply both "kill" and mortify as in the Catholic(?) idea of the "mortification of the flesh", wherein one self-inflicts physical punishment in atonement for sin.

From there, the figure of the hangman is I suppose a manifestation of the sort of "big Other" kind of internal figure, representing self-infliction of suffering "on behalf of" an external idea, and at the same time also projecting the aforementioned person onto this figure.

In the sestet, the idea of "the wedding of delight and that which will destroy us all in time" is that of the complex relationship and interplay between desire and self-destruction, between the want of something both for the potential pleasure that it can bring and the destruction that it also brings, between the Freudian "death instinct" (Thanatos) and "life instinct" (Eros), its "consummation" being the aforementioned "hanging"; the Event in which tensions between these two opposing forces are released; their violent collision as the subject "gives in" and lets be what may.

(I feel as if I haven't explained myself properly at all and am only coming across even more pretentious. :/)
