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 ask me why there's an emptiness inside
Come on, be calm, be cool
Do something you like, whisky 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, 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
