Now you know.

So know you know
I blurted it out.
You were never supposed to know.
But now you know.

Nothings changed
It hasn't got easier.
I still reach for the knife.
Nothings changed.

Now you know
Everything feels worse.
Fearful for what you might do.
Now you know.

Everything's change.
The way we talk.
The look in your eyes when you look at me.
The extra blood that leaks.

Know you know everything's changed!
