我哭谁心疼别哭我心疼
[wŏ kū shéi xīn téng bié kū wŏ xīn téng]
It can be translated as 'If I cry who will feel for me don't cry because I am pained by your sorrow', it indicates deep emotion towards someone, showing how much care or love the speaker has for another individual, and at the same time, a sort of self-inflicted pain.
