撕掉最后一丝逞强说再见撕扯最后一缕阳光说拜拜
[sī diào zuì hòu yī sī chĕng qiáng shuō zài jiàn sī chĕ zuì hòu yī lǚ yáng guāng shuō bài bài]

Both expressions denote making a definite break from something with finality; it's about leaving behind and letting go while closing one's life chapter or severing old relationships or ways with resolve.
