《Heart Attack》的歌詞如下：
Verse 1：
Oh my god what have I done
I feel like I'm going crazy
My heart's racing and I can't catch my breath
I don't know what to do
Chorus：
I'm having a heart attack
I feel like I'm dying
It's not my fault, it's not my fault
It's just the way I am
Verse 2：
I feel like I'm on the edge
Of losing control again
But I won't give in, I won't give up
I'm stronger than this
Chorus：
I'm having a heart attack
I feel like I'm dying
It's not my fault, it's not my fault
It's just the way I am
Bridge：
It might be time to quit
But I won't give in just yet
I'm hanging on by a thread
But I won't let go
Chorus：
It might be a heart attack
But I won't let it defeat me
It might be time to change
But I won't give up on me
Outro：
It's not my fault, it's not my fault
It might be time to start over again.
