i need some help

I am having a hard time getting an ID on this song I heard on the radio. I think the lyrics go like this:

I am I am I said
I'm not myself
I'm not scared
and i'm not ("for sale" maybe)

I couldn't tell for sure if thats really what is being said, it was played on a modern rock station. If you have any ideas please help me out.
