Help!

I've had a song stuck in my head and I have no clue where I heard it or what it is. I think the lyrics go something like:
Vanity,
Nothing I do does a thing for me,
Can this be?
I am the worst thing thats ever happened to me.

Anyone know who it's by or the name of it? Thanks!

i tried typing the lyrics into google, it usually works

but The Getaway - the name of the band - seem to not exist to people who don't know a good band when they hear them

they're awesome eh?
no clue what the song is though sorry

Thank you. I listened to one of my old CDs and heard it. It's a song by a band called Jonny Was... Their lead singer is actor Shane West. I still don't know the name of the song but at least I can hear the whole thing without having that same line stuck in my head all the time.
