痛切

tòng qiè de rèn shi dào zì jǐ de cuò wù

痛切地认识到自己的错误

come to see one's own mistake with feelings of deep remorse

tòng qiè de fǎn xǐng

痛切地反省

reflect on with deep remorse

wǒ wú fǎ qū sàn yíng rào zài wǒ xīn tóu de tòng qiè gǎn shòu

我无法驱散萦绕在我心头的痛切感受。

I could not erase from my mind the poignant thought.
