Nostalove 

Definition: (noun) The bittersweet longing and profound affection felt when reminiscing about a cherished younger sister, a profound pride in her accomplishments, interwoven with an overwhelming sadness arising from her absence.

Nostalove combines "nostalgia," representing the wistful yearning for moments past, and "love," encapsulating the deep affection and adoration one holds for their sister. This word reflects the intricate emotions that arise when missing someone dear, particularly when acknowledging their growth and accomplishments while grappling with the sorrow of their absence. It captures the essence of your sentiment, reminiscent of the evocative language found in classic poetry.

Example sentence: "In the depths of my heart, a tapestry of Nostalove unfolds, as I recall the moments shared with my little sister, her absence leaving a void that brims with pride for her journey, yet aching with the realization of her physical absence."
