A Carved Heart

I have this thing on my arm
It shows me my past
I call it a tattoo
But thats not what it is

After slitting my hand
One day when I was mad
I put my knife against my wrist
And began to carve away

I cut a point
And wedged it along
Deeper and deeper
I drew the blood

Soon, the shape emerged
And I stared deep into the cut
A bloody heart shone back at me
Signifying my losses
