Wow my mind gets stuck in a cage sometimes as well. I know what it feels like to be stuck inside longing to be out and run away. The best way I found to get out, is just to go on a run with some loud music. But really what I am saying with that is just try not to think about it, if you dwell on it, the cage gets smaller, if you distract yourself and your mind, you will see the exit or you wont think about the "bars" so much.
