It is not just you alone in exile. Abraham, Isaac and Jacob and all the generations of their children, as well all the heavenly host—in fact, the entire creation—all is unfulfilled, in exile and imprisoned.
Even the Creator Himself locks Himself into prison along with His creation.
At every turn, light awaits you to release it from its prison. And with it, the entire world.

Exile means to be forced away from a cherished place ,or country. Since we were taken out of the Gan Eden we are in exile and working had to live as Chavah and Adam when they were told that nothing from now on will be free. Late, of course Moshe Rabbeinu toook us of Egypt and brought us to the Promised Land. Yet, those living then didn't behave to the level that Moshe Rabbeinu's proclaimed: "Justice, Justice thou shall pursue" and, in time we lost the L and again; hence galut. If H' is also feeling imprisoned is out of sympathy with us his children, H' gave free will but it meant to live a life bederech., and it takes an effort to walk the path as directed. When this reversal is not happening, of course, H' also feels in prison. I think this is metaphorically implied becaus H' is definitely a free unique agent of creation. with no strings attached as we humans are.
