Darkness becomes a part of me

I hide behind my bed post,
I can see its black wings peaking out of the sides,
I was always, the perfect one, the one with streight "A's"
It was in me, she would always confide...
She was the suicidal one...The one with all the issues...Not I...
I'm scared to death of this creature,I'm not going to lie...
But finally, it takes me, takes me to it's land...
Where darkness becomes a part of me...
And my kitchen knife, finds it way into my welcoming hand...
