You're in me.

—I love you, I-I-I love you, I do! And I have been trying not to say it, I have been trying so hard to mash it down and ignore it and not say it... but it was never gonna work out because I love you. I am so in love with you. You're in me. 
It's like you're a disease,
it's like I'm infected by Mark Sloan. I can't think about anything or anybody, I can't sleep, I can't breathe, I can't eat. And I love you, just all the time and every minute of every day. I love you.
