葬在脑海的未亡人溺如深海的痛心人
[zàng zài năo hăi de wèi wáng rén nì rú shēn hăi de tòng xīn rén]
This is a dramatic way of describing unprocessed feelings towards lost loved ones. 'Buried in my brain' suggests that the deceased (metaphorically or literally) haunts their mind continuously, while 'Drowning in painful heart' means being immersed in sorrow.
