這首歌的旋律非常悲傷，適合心情低落的人聽聽，歌詞如下：
"It's the hardest thing
Gonna let you walk away from me, into the setting sun
Wish I could follow you, but you're all alone
You're gone, gone, gone
It's the hardest thing
But I'm gonna make it alright
I'm on my own again
But I'm alright
It's the hardest thing
And it eats away at me every night and every day
You could feel so brand new
But now you're all I think of
And I cry and I cry and I cry
I remember the first time you told me you loved me
I said, "It was just a phase"
And now I look back and I realize that I was wrong
I can't get you off my mind, don't know what to do
And now it's the hardest thing
But I'm gonna make it alright
I'm on my own again
But I'm alright
It's the hardest thing
And I know that it won't be easy
To walk away from everything
But you can be sure that I'll make it alright"
