[Verse]
I am the angel that can see into your heart
I sense the darkness that is tearing you apart
But I know a true place that you always try and part
And I hear the screams that you keep buried down inside

Say yeah

[Chorus]
The world that you're alone in
Could be your serotonin, yeah

[Verse]
A million thoughts are racing round and round your head
But as the sunlight starts to creep across your bed
They're forming pictures and those pictures turn to words
And they make sounds, that sound like nothing you have heard

Say yeah

[Chorus]
The world that you're alone in
Could be your serotonin, yeah
The world that you're alone in
Could be your serotonin, yeah
[Bridge]
So make your home
In the shadows that you find
Raise your flag
Amongst the rubble in your mind
The waking up can be so hard sometimes
But when your eyes are open
You don't know what you might find
So I say yeah

[Chorus]
The world that you're alone in
Could be your serotonin, yeah
The world that you're alone in
Could be your serotonin, yeah
