I can't 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've got my soul and 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 You're in my system, baby Deep in my system You've got me going crazy Inside my system You're in my system, baby Deep in my system (oh) You've got my soul and body You're in my system You're in my system, baby (You're my system) You've got me going crazy (Deep in my system) You're in my system, baby (Oh, don't you know?) You've got my soul and body You're in my system You're in my system, baby Deep in my system You've got me going crazy Inside my system You're in my system, baby Deep in my system You've got my soul and body You're in my system
