想让我把刀往自己心扎吗
[xiăng ràng wŏ bă dāo wăng zì jĭ xīn zhā ma]
'Do you want me to stab myself with a knife?' It's a very expressive way of indicating intense frustration or deep emotional distress and sorrow. However, it could be taken as too dramatic in literal terms and is more figurative, showing feeling deeply wounded by someone or something.
