I've got a woman on my mind
She's been on it for three days and nights now
And I don't wanna be that way
But my thoughts run wild on the pillowcase
'Cause I can't help but wonder if she's moving on

And I toss and turn 'cause my heart, it burns
For a love I once held in my hand
Worry is a sickness, worry is a sickness
And I'm worried sick over you

I haven't left my house since you left my house
I just know I'm gonna see you if I go out
I've been breaking out in fever and losing weight
Girl, I've been diagnosed with a heartbreak

And I toss and turn 'cause my heart, it burns
For a love I once held in my hand
Worry is a sickness, worry is a sickness
And I'm worried sick over you, yeah

I'm worried sick, babe
I don't know, I don't know if I can't make it through
Baby, I'm infected with the thought of you

And worry is a sickness, worry is a sickness
Yeah, yeah, yeah

Worry, worry, worry is a sickness
Worry, worry, worry is a sickness
And I'm worried sick over you
I'm worried sick over you
