心软成病我已病入膏肓
[xīn ruăn chéng bìng wŏ yĭ bìng rù gāo huāng]
Heart disease in the Chinese culture often means being overly sentimental, sensitive or compassionate which affects one's rational decision making. The term used here is metaphorical for an extreme case: One’s empathy and affection reach a point where the 'condition' is incurable, emphasizing excessive sensitivity that makes them feel unable to make reasonable decisions anymore, or too easily moved and thus emotionally weakened.
