I love you so much it's killing us both : a novel, or an annotated mixtape / Mariah Stovall.

Enhanced descriptions from Syndetics:

Susan Choi's Trust Exercise meets Nick Hornby's High Fidelity in a Black woman's coming-of-age story, chronicling a life-changing friendship, the interplay between music fandom and identity, and the slipperiness of sanity

Set in the suburbs of Los Angeles and New York City, I Love You So Much It's Killing Us Both is an immersive journey into the life and mind of Khaki Oliver, who's perennially trying to disappear into something- a codependent friendship, an ill-advised boyfriend, the punk scene, or simply, the ether. These days it's a meaningless job and a comfortingly empty apartment. Then, after a decade of estrangement, she receives a letter from her former best friend. Fiona's throwing a party for her newly adopted daughter and wants Khaki to join the celebration.

Khaki is equal parts terrified and tempted to reconnect. Their platonic love was confusing, all-consuming, and encouraged their worst impulses. While stalling her RSVP, Khaki starts crafting the perfect mixtape-revisiting memories of formative shows, failed romances, and the ups and downs of desire and denial-while weighing the risks and rewards of saying yes to Fiona again.

One song at a time, from 1980s hardcore to 2010s emo, the shared and separate contours of each woman's mind come into focus. Will listening to the same old songs on repeat doom Khaki to a lonely life of arrested development? Or will hindsight help her regain her sense of self and pave a healthy path for the future, with or without Fiona?
