I know this is sounds dumb given the degree of pain you've experienced but if you can use a biofeedback technique : close your eyes and think about that beautiful sky and the things and places that bring you joy, them take slow deep breathes holding your breath for one second before you slowly exhale through your pursed lips, letting only a tiny bit of air out at a time until you have no air in your lungs, then take a deep breath in.
If the pain is severe, blow your air out in small faster breathes kind if like Lamaze breathing.
I love you Charlotte. Take a pain pill when you get home too. First 24 hours be aggressive with the pain management
