Being scared is a natural human emotion that prepares us. It’s good to have a little of that feeling in weird situations, but I agree that it should not consume you. I don’t want to scare you further, but from an “outsider opinion”, the details in your OP read like the start to a Netflix doc. Your end goal should be to document everything officially, hope for the best, and prepare for the worst. Then you can go about your life comfortably knowing all bases are covered.
