get sby through即係點解呀??

get x through 在這句歌詞中的意思是指:

去面對或渡過某種難關或處境

the words I need to hear to: 直譯 是 我需要聽到的說話. 那暗喻的意思是已離開的愛人曾對自己說過的話. 人既不在, 現在只好回憶那些話來作自我安慰了.

因此全句的大意是:

自你去後, 我只好回想以前你曾對我說的話, 令自己好過一點.

以下有更多字典例子幫助理解 get x through 的意思:

get (sb) through sth (DEAL WITH)

deal with a difficult or unpleasant experience, or to help someone do this:

I don't know how I got through the first couple of months after Andy's death.
We need to conserve our supplies so we can get through the winter.

自你去後, 我只好回想以前你曾對我說過的話, 令自己的日子好過一點.

另補充 「gone」 一字, 和中文的「去」字一樣, 【不一定】是解死亡的. 歌曲的 MV 中, 可見並非一個單一故事: 其中一個故事是一位老伯想念他已死去的太太, 在此 gone 是解死去了; 但另一位年輕的孕婦是在想念她在戰場上的丈夫的, 最後一幕可見他有報平安的短訊 --「I'm ok, I miss U」使她開懐 (若她丈夫死了, 在那軍方聚會中, 她不可能笑得出口的). 因此, gone 在此只是解不在, 已離去的意思.

I always needed time on my own
I never thought I'd need you there when I cry
And the days felt like years when I'm alone
And the bed where you lie
Is made up on your side
When you walk away I count the steps that you take.
Did you see how much I need you right now?

When you're gone, the pieces of my heart are missing you.
When you're gone, the face I came to know is missing too.
When you're gone, THE WORDS (I need to hear to) always GET ME THROUGH the day,
and make it OK.
I miss you.

先談get (sb) through sth的意思是：to deal with a difficult or unpleasant experience；or to help someone do this.（意思是：面對、應付一些艱難、不愉快的經歷；或幫助某人面對、應付艱難、不愉快的經歷）
所以，歌詞是說到：
當你死後，
那些我需要耹聽的話，總是幫我經過那些日子。

希望幫到你！
