wolf in sheep's clothing

I am a wolf in sheep's clothing I am a fake, the smile I have isn't what people think, it's a cry for help, but to other people it's just my "I'm fine" I talk so I don't cry, I laugh when I feel dead inside, but after awhile the numbness turns into a dread in my head, the words I thought could never hurt me, takes my hand like a cold beast, I am a wolf in sheep's clothing and I'm sorry for the way i think.
