You're holding it in, you're holding it back

You're drowning the pain, drowning the sad
你淹沒了傷痛 淹沒了悲傷
Trying to find something, something to believe
試著尋找一些可以相信的東西
Trying to find a way, a way to believe
試著尋找一種方式 來相信自己
You say it won't hurt you
你說那樣對你來說沒關係
It won't last forever
不會持續到永遠
Just keep telling yourself, yeah
只是不停地對自己說 是的
That it's not real
那不是真的
Just let it out, just let it out
放開吧 放開吧
Come on now, come on now
現在 就來吧 現在
Just let it out, just let it out
放開吧 放開吧
Come on now, come on now
現在 就來吧 現在
You keep pushing it down, keep pushing it down
你一直壓制它 一直壓制它
Trying to make it all okay, yeah
試圖讓它變得好起來 是的
But you're holding it in, you're holding it back
但你正在忍耐 正在克制
Trying to make sense of what's real and what's fake
試圖弄清楚什麼是真實的什麼是虛假的
And what's yours and what's theirs
哪些是你的 哪些是他們的
Trying to find a way, a way to believe
試著尋找一種方式 來相信自己
You say it won't hurt you
