I can hardly
Breathe at the thought of you
Just your presence
Gets me so confused
It must be that you
Are more than you think to me
Yet I have to act like I'm okay
I'm not okay
It goes much
Deeper than your day-to-day crush
From back in your school days
It goes much
Deeper than those songs
That I hear with a sentiment
(It's) more than that cause you're in my system
There's nothing I can do
There's nothing I can say
You're in my system, baby
Deep in my system
You've got me going crazy
Inside my system (oh yea)
You're in my system, baby
Deep in my system (deep in my system)
You've got my soul and body (my body)
You're in my system

I can't hardly talk sometimes
When we're face-to-face
There are times when I don't need to say a word
'Cause I know you know
There are times when you just over-analyze me
But you know I don't really care
'cause I really care
You're in my system, baby
Deep in my system
You've got me going crazy (going crazy)
Inside my system (oh)
You're in my system, baby
Deep in my system
You've got my soul and body (body)
You're in my system
From my head to my skin
To my arms all my limbs
They can sense it
From my heart through my chest
And my lungs down my waist
I can feel it
From my spine to my hips
And my knees to my toes
They be shaking
But my mind and my brain,
How they drive me insane
'Cause you're right here
Taking over my system, yea

You're in my system, baby
Deep in my system
You've got me going crazy (going crazy)
Inside my system (oh)
You're in my system, baby
Deep in my system
You've got my soul and body (body)
You're in my system

From my head to my skin
To my arms all my limbs
They can sense it
From my heart through my chest
And my lungs down my waist
I can feel it
From my spine to my hips
And my knees to my toes
They be shaking
But my mind and my brain,
How they drive me insane
'Cause you're right here
Taking over my system, yea
