Me without You

What's wrong with me?
What's wrong with you?
We seem to be lost at sea
What happened to us?
Our hearts used to beat as one...
Or so it seemed?

What do you mean the problem isn't you?
You're the one that left, alone, without me.
What the hell happened to us?
Please tell me why you left me all alone?
I need to know what I did so wrong?

Tell me now, I don't understand
Why you left me so suddenly?
I don't like this,
Not seeing you in my heart
It's like part of me is gone
And that part of me is you.
