I feel like a puzzle and I can't find my missing piece

(...)
Are you lost or incomplete?
Do you feel like a puzzle, you can't find your missing piece?
Tell me how do you feel?
Well I feel like they're talking in a language I don't speak
And they’re talking it to me.
(...)
So you don't know where you're going and you wanna talk
And you feel like you're going where you've been before
You tell anyone who'll listen but you feel ignored
Nothing's really making any sense at all, let's talk
Let's talk, let's talk, let's talk.
