我可以坚强到世界都心痛
[wŏ kĕ yĭ jiān qiáng dào shì jiè dōu xīn tòng]
'I can be so strong that even the world would ache.' This phrase conveys a sense of intense self-reliance and resilience to the point where one's strength becomes almost painful, reflecting both determination and hidden pain or vulnerability.
