我已习惯没你的世界
[wŏ yĭ xí guàn méi nĭ de shì jiè]
It translates to 'I Have Gotten Used to A World Without You,' suggesting the person has grown accustomed to life post-loss - perhaps after the departure of someone significant such as in a romantic relationship or friendship. Although difficult and sad initially, the individual learns to accept and adapt to this new situation.
