Wicked

I am the pain you feel inside, I am the darkness you try to hide. I'll eat at your soul, You'll have no control. I am the voice in your head, I am the one you most dread. I mess with your mind without a care, I will make you feel weak with despair. You try to fight what you really fear, I will corrupt your soul, my dear. When those thoughts had finally disappeared, I came back with what you feared. Your sanity will cease, There is no sweet release. I am the wicked who uses hate, I am now the controller of your fate.
