Carpe Diem is a Latin aphorism that usually is translated as “seize the day”. The phrase is used to express the imperative of living life to the fullest, of making the most of every situation, of enjoying every moment of life and of capturing the beauty of it in everything and everyone, since, as mortals that we are, life will eventually come to an end.
The speaker is explaining that they are feeling helpless and like an outcast. The word 'Bootless' means useless, therefore their cries to heaven for help are useless. Hope this helps!
