心冷致病可你是命
[xīn lĕng zhì bìng kĕ nĭ shì mìng]
This translates as a situation of emotional numbness that almost brings illness ('a frozen heart' leading to illness/disease). But then paradoxically, this condition is followed by stating “yet you are my life” which implies that despite feeling emotionally cold or distanced toward everything else in one's life, their significant other still remains indispensable.
