In the middle of the night
Every minute, every time
All I think about is you
Pain in my side
In the bottom of the wine
All I think about is you

I see your face when I leave
Fast asleep next to me
Here's to that, you're everything
You're what I need, my baby

Tell me that you want me and need me too
Tell me that I'm somebody you can't lose
What can I do? What can I do?
My serotonin, my tattoo
I'm not myself without you

People asking me why there's an emptiness inside?
Come on, be calm, be cool
Do something you like, whiskey tonight?
Do something you used to do

Tell my therapist I'm fine
I'm done lying every time
But I'm not fucking fine

Tell me that you want me and need me too
Tell me that I'm somebody you can't lose
What can I do? What can I do?

My serotonin, my tattoo
I'm not myself without you

Oh-oh-oh
Tell me that you want me, oh
And you need me

My serotonin, my tattoo
I'm not myself without you

Tell me that you want me and need me too
Tell me that I'm somebody you can't lose
What can I do? What can I do?

Tell me that you want me and need me too
Tell me that I'm somebody you can't lose
What can I do? What can I do?
My serotonin, my tattoo
I'm not myself without you
