《How to believe》的詞曲由艾薇兒·拉維尼完成，其歌詞如下：
Verse 1：
How to believe when every morning
I wake up and see your face
How to ignore the voices in my head
That say I'm not good enough
Chorus：
But I won't give up
I won't give in
I won't give up on us
I've been fighting every temptation
Trying to keep us afloat
How do I keep my faith when I'm feeling so doubtful
So alone in this
Verse 2：
How to be okay when I'm feeling like this
How to move forward when I'm scared to look behind
Chorus：
But I won't give up
I won't give in
I won't give up on us
'Cause I know we'll get through
Through everything if we stay together
Bridge：
It's the little things you do
That make me believe we can make it through
Chorus：
But I won't give up
I won't give in
No I won't give up on us
Outro：
Because I how to believe...
