Right, I think your verses are very good, they've got some interesting word choices, strong rhyming pattern and you've incorporated your emotions and experiences very well, however, I feel like chorus is very monosyllabic, it just lacks substance and words. I'm not saying you can't have a short chorus, but your falling sky idea is really good, so I think you should loose the repetition and think of a chorus structure that platforms your ideas better, having the title of the song in the chorus might help. Remember, although your writing about your experiences you still have to make your lyrics understandable and relatable for your listener
