Oh, wow. I hope you’re okay!
But this is precisely why I would consider being a plastic surgeon. It’s all about finesse, it’s lovely and clean work, and you do make a difference to people. They might not save your life per se (unless you have necrotising fasciitis, but I really hope that no one out there ever gets that), but they can repair your nerves and your joints and return you to a level of function very close to what you were prior to surgery. And they put so much effort into making it look like you never had surgery.
Thanks for sharing your experience, and best of luck with your studies!
