孤独是国我是王思念是病我是医
[gū dú shì guó wŏ shì wáng sī niàn shì bìng wŏ shì yī]
Using metaphor, it depicts isolation as a kingdom and oneself as its ruler; while also presenting longing and yearning as an illness for which only oneself can provide healing. It beautifully captures feelings of solitude and self-reliance mixed with pining.
