My Deadly Disease

Really I'm being pretty hypocritical.
Lying is the worst act anyone can commit,
So that I'm lying to myself is pretty pitiful.
I'm not over us I have to admit
And it kills me to see you with her every day,
Sitting so close and touching her leg.
It stabs me in the heart, as sharp as the barb on a stingray
And the poison jealousy seeps into my veins and I'm trying to hold myself together like a cracked egg.
When you look up and catch my eye,
Everything in my system gets a shock.
My thoughts wave goodbye
And the whole world stops.
But then the moment ends and all you see is her.
My head knows you're not but my heart screams "Mine!"
I need to come back down to Earth.
I'm deathly ill but I tell everyone I'm fine.
Why is there no cure for this disease?
On some stupid commercial,
A man screaming "We can fix it, it's our guarantee!"
Something to numb the pain and stop it from being hurtful,
Something new to get addicted to.
It's got to have symptoms of memory loss and numbness
To make me forget my old addiction to you.
