The Devil Within

I'll keep quiet
 You won't even know I'm here
 You won't suspect a thing
 You won't see me in the mirror
 But I crept into your heart
 You can't make me disappear
 'Til I make you
 
 I made myself at home
 In the cobwebs and the lies
 I'm learning all your tricks
 I can hurt you from inside
 I made myself a promise
 You would never see me cry
 'Til I make you
 You'll never know what hit you
 Won't see me closing in
 I'm gonna make you suffer
 This hell you put me in
 I'm underneath your skin
 The devil within
 You'll never know what hit you
 ♪
 I'll be here
 When you think you're all alone
 Seeping through the cracks
 I'm the poison in your bones
 My love is your disease
 I won't let it set you free
 'Til I break you
 You'll never know what hit you
 Won't see me closing in
 I'm gonna make you suffer
 This hell you put me in
 I'm underneath your skin
 The devil within
 You'll never know what hit you
 I tried to be the lover to your nightmare
 
 Look what you made of me
 Now I'm the heavy burden that you can't bear
 Look what you made of me
 Look what you made of me
 I'll make you see

 You'll never know what hit you
