I'm inside your head

I am the reason you cannot sleep
I am the voices in the back of your head
I know the secrets that you've never said
I'm always with you and I'll never leave

You see the world as your own
And you don't give a [bad word] 
About anything other than yourself
You won't stop until you have
Your greedy hands on all
That ever brought and it was happiness
This is how you accepted my presence
And now you will never get rid of me
Screaming as loud as you can
It doesn't make a difference
You will never be without me

I am inside of your head
I won't leave until your dead
I am inside of your head
I am the reason you bled
I am inside of your head
I won't leave until your dead
I am inside of your head
I am the reason that you bled
It's too late to turn back now
The world is not your own
Another minute put to rest

Oh!

I have your soul
You will perish
I have your soul
You will perish
I have your soul
You will perish
I have your soul
You will perish
I have your soul
You will perish
I have your soul
You will perish
I have your soul
You will perish
