If youāre interested in the neurobiology and psychology of grief, I read the grieving brain for a class I took and found it accessible and fascinating (Linked)
ive also already recād āa grief observedā by c.s. Lewis on here but it is truly one of the most poignant and beautiful things Iāve ever read, a heartbreaking personal meditation on loss, faith, and love. if youāre cool with reading something devoutly religious, I canāt recommend this enough. Iāve attached a photo of the opening lines.
