我有病叫不能没有你我有药叫不能失去你
[wŏ yŏu bìng jiào bù néng méi yŏu nĭ wŏ yŏu yào jiào bù néng shī qù nĭ]
Translating to 'I have an illness called cannot do without you and the medicine is I cannot lose you', it poignantly illustrates extreme dependence and desperation in loving someone, implying they provide life's essence.
