A Constant Call to My Fall

[CRNDLSM]

I don't understand the 'sale' in the title, I can picture a sell, like a man (because of love letter and ... wedge) sold himself (convinced you of his attractiveness as a man) and you have remorse over thinking about buying what he sells (not quite buyers remorse), since the despair seems to come from the wedge it created.  

I think it would look better like this:

the sky falls
mace and chains
whips and fire
as you wait
for my love letter
your murky wedge

between me & God

I must confess
I see snakes
and worms
and hear
the sounds
of much hissing

I like how 'I must confess' and 'of much hissing' are positioned and confess somewhat rhymes with wedge, cool.  I just think with that in mind you might change the first line, the sky falls is bland, hope this helps!
