Well done!! I really like, as well as the fact that you've resolved the contradiction, the complexities that you've given to Lady Macbeth here, the gnawing of her heart giving way to the (deceptive? she says so now, but is she now self-deceiving?) limpid clarity of her brief maternity, which she rejects in retrospect, but then circles back to thoughts (hopes, fears)of love.
also, great line - "That squall'd, and suck'd and rested in my arms"!
Oh, and the echo of "thrice the brinded cat hath mewed..." - oh, chills! - it just now comes to me that the power of the Witches (or the sickness of Scotland) is at work here - sorry for being slow!
