"Crazy" 是由Britney Spears演唱的一首歌曲，以下是其歌詞：
Chorus:
Oh my god I'm going crazy
I'm feeling it all, it's true
Oh my god I'm feeling nothing
No one knows how I'm feeling through
Verse 1:
Oh no no no, it's more than I can take
Feels like my heart is breaking into pieces
It's over and over, this time I know it's true
No need to fight anymore
Chorus:
Oh my god I'm going crazy
I'm feeling it all, it's true
Oh my god I'm feeling nothing
No one knows how I'm feeling through
Bridge:
You never seem to understand
The words I say, how could you ever be
Now that you're gone, it doesn't matter
Because I love you so much anymore
Chorus:
Oh my god I'm feeling crazy
I'm feeling it all, it's true
Oh my god I'm feeling nothing
No one knows how I'm feeling through
Outro:
Oh my god, I'm feeling lost without you
I don't know what to do without you baby
I need you back, I need you back now baby.
