The quote reflects a profound sense of disillusionment and internal conflict. As the initial excitement of desire fades, it is replaced by a heavy, almost unbearable sensation that lingers in the mind. The use of the word "ashen" conveys a sense of decay and loss, suggesting that what once felt exhilarating has now transformed into something dark and troubling.
The mention of a "grey neuralgic day" adds to the bleak atmosphere, evoking a dreary, oppressive environment that mirrors the speaker's emotional state. It emphasizes how the outer world can influence one's inner turmoil, suggesting a deep connection between external circumstances and internal feelings of dread and melancholy.
