My own worse enemy

I look at her,
She stares at me.
I want to leave
but I can't.
I blink twice,
Then, she follows.
I take a breath,
we swallow.

She opens her mouth,
and repeats all of the words that have hurt me before.
She's yelling and crying
I can't take it no more.
She continues to spew
Insults and threats,
I start to tense up,
My face starts to sweat.

This is the end
I won't let this go on
She needs to leave.
To stop.
To be gone.
This is the person
who I've considered a friend,
when all this time she has hurt me over and over
and over again.

I step up to the plate,
about to take a swing.
I think to myself
Is this the right thing?
It's too late to answer
I've already aimed,
My hand hits something
I feel sorta ashamed
But as I get near,
I realize,
I am the cause of my own fear.

But before I can stop to think any deeper,
I hear a crash
as some glass hits the sink,
I know she feels weaker
as the mirror breaks
into a thousand,
Brilliant,
pieces.
