You 

Are my obsession

You 

Are my drug

You are my everything

My favorite quote says

"You don't cross my mind, you live in it."

You 

Are my obsession

Without you

I have no purpose

Without you 

I'm lost 

Without you

I have no reason to 

Dress to impress

You 

Are my obsession

I guess you could say

If not you

It would have been 

Some one else

It's just in 

My nature

You 

Are my obsession

It could have been 

Anybody

But my obsession is 

You

This one I'm not too too proud of...
