Do You Wanna Know

I feel so sad I feel so down
You think it's because you're around
But it's not you , it is me
Look at me who do you see
Do you wanna know , oh no
Do you wanna know , no no no
Do you wanna know , do I have to tell you
Do you wanna know , do I have to tell you
Do you wanna know , I can't explain
Do you wanna know , only feel pain
Do you wanna know , no no no no
Do you wanna know
Sometimes I'm good sometimes I'm bad
Sometimes I'm day sometimes I'm night
Like Doctor Jeckill and Mister Hyde
I wanna know who am I
