我有病但你没药
[wŏ yŏu bìng dàn nĭ méi yào]
The meaning is literally 'I'm crazy but you don't have medicine (which could treat me)'. Here 'crazy' can refer to a unique character/personality, while lacking 'medicine' implies the other person fails to meet such uniqueness or does not accept it. There may be a hint of disappointment and sarcasm.
