I'm going underand this time I fear there's no one to save me

*going under 原指“沉没、下沉”，在这里比喻“精神上垮掉、被情绪淹没”

我欲沉沦堕落，又恐无人相救

This all or nothingreally got a way of driving me crazy

*all or nothing“孤注一掷的”，形容一种极端的状态——要么全部拥有，要么一无所有

这非成即败的爱让我逐渐失去理智

I need somebody to heal

我需要有人治愈

Somebody to know

有人倾诉

Somebody to have

有人陪伴

Somebody to hold

*hold（抱住）通常指持续一段时间的抱，带有“不放手、守护”的意味; "Hold me tight"（紧紧抱住我）

有人相拥

It's easy to say

这知之非难

But it's never the same

却行之不易

I guess I kinda liked the way you numbed all the pain

我想我还是喜欢你麻木伤痛的样子

*numbed all the pain 麻木了所有的痛苦

Now the day bleeds into nightfall

*bleeds into nightfall“Bleed”原意为“流血”，在此用作诗意表达，形容白天“流逝”进黑夜的画面

血染残霞，夜幕将袭

And you're not here to get me through it all

*get me through it all 帮我度过这一切

你不在此，与我披荆斩棘

I let my guard downand then you pulled the rug

*let my guard down卸下防备，放下警惕

*pulled the rug字面意是“抽走脚下的地毯”，引申为“突然背弃、令某人措手不及”

我毫无防备，你的离开令我措手不及

I was getting kindaused to being someone you loved

*kinda是kind of的口语简写，意为“有点儿”

我也逐渐习惯了成为你爱过的人

I'm going under and this time I fear there's no one to turn to

我欲沉沦堕落，又恐无人相助

This all or nothing way of loving got me sleeping without you

这非成即败的爱让我与你异地而眠

Now, I need somebody to know

我需要有人倾诉

Somebody to heal

有人治愈

Somebody to have

有人陪伴

Just to know how it feels

只要能感同身受

It's easy to say but it's never the same

这知之非难，却行之不易

我想我还是喜欢你助我逃脱的样子

Now the day bleeds into nightfall

血染残霞，夜幕将袭

And you're not here to get me through it all

你不在此，与我披荆斩棘

I let my guard down and then you pulled the rug

我毫无防备，你的离开令我措手不及
