Meaning of "Look Up" by Chairlift

The lyrics of "Look Up" seem to touch on themes of exhaustion, disillusionment, and striving for something beyond the current circumstances. The mention of running out of pretending and having nowhere left to run can be seen as a feeling of being trapped or stuck in a cycle that seems never-ending. The idea of meeting our end on bridges built across the sky could symbolize the inevitable end of life and the acceptance of mortality. The desire to want nothing at all might speak to a longing for simplicity or a release from the pressures and expectations of life. Overall, the song seems to capture a sense of weariness and yearning for something more meaningful.
