And now you scare me

I see your name
and my stomach knots
this isn't a happy feeling
it feels like I've been shot

we used to be friends
i thought I'd be cool
to get to know you
but guess i was a fool

and now you scare me
i don't know how to say
I'm gonna try to protect the others
you better keep away

cuz we're watching you
and you'll never know
i tried to be your friend
now I'm your deadliest foe
