Two People in One

I look in the mirror, but it's not myself
It started so soon, but I couldn't find help
something ripped up my chest and was shoved from my soul
I felt like I was falling into a deep hole
within myself, but everything was black
I could see everything, but my body lacked
my own self control, something took over me
It was speaking for me, it was moving for me
I felt all this darkness, it pushed me away
I thought I was dying, my soul just felt strayed
The legs started crashing, my voice started screaming
I looked over the person that took my body's shape
As I ran away, she felt it was a race
do I know who she is? Does she know it's my face?
My friend, my love, he knows I love him.
But in the end, I just can't win.
this evil, dark soul, taking over my life
The reaper played cards, and he gave her his scythe
I screamed for help, but I wasn't heard
I'm stuck in my mind, the only thing cured.
She walks in my body
She talks in my body
Her evil mind takes over, but is seen by nobody
What will I do?
What can I say?
I'm stuck for eternity, it's over today
I couldn't fight. I just couldn't win.
My will was destroyed by this evil girl's sins.
My luck just ran out, lost the sight of my sun
Is this really what happens with two people in one?
