Keep this as a secret ?

I've got a secret.
It's on the tip of my tongue, it's on the back
of my lungs.
And I'm gonna keep it.
I know something you don't know.

It sits silence, eats away at me.
It feeds like cancer. This guilt could fill a
fucking sea.
Pulling teeth, wolves at my door.
Now falling and failing is all i know.

We all carry these things inside that no one
else can see.
They hold us down like anchors. They drown us
out at sea.
I look up to the sky, there may be nothing there
to see.
But if i don't believe in him, why would he
believe in me?
