I thouroughly enjoyed reading this and with a strong sense of déjà vu. I feel like I dreamt of reading this story at some point before you wrote it.

Guardian angels definitely exist. Here's a great story I read over two years ago that I have never forgotten. https://medium.com/illumination-curated/guardian-angels-saved-my-life-5c4c840bafbd I read Rebecca all the time. You and everyone else should too. When you have the time look through her profile and see what draws you in to read.
