Radiohead I can't lyrics

Please forget the words that I just blurted out
It wasn't me it was a strange and creeping doubt
It keeps rattling my cage
There's nothing in this world will keep it down

Even though I might
Even though I try
I can't

So many things that keep keep me underground
So many words that I that I can never find

If you give up on me now
I'll be gutted like I've never been before

Even though I might
Even though I try,
I can't
