掏心掏肺搞得现在没心没肺
[tāo xīn tāo fèi găo dé xiàn zài méi xīn méi fèi]
'Giving one’s heart and soul away and ending up having neither.' This phrase means someone gave so much effort and emotion in a relationship or cause that they became apathetic, indifferent, and ultimately lost genuine feelings and emotions.
