Accept that risk is never zero, and all people live with that circumstance every single day.
Getting to a place of acceptance is what gets me through HA. And, I do get what you're going through. I have a bat story that would probably make your hair stand on end and I had to put acceptance into action, and it did release me from the fear state I was like paralyzed in after the exposure I and my family had. We have no choice but to accept that we are part of nature, we interface with it, and sometimes it takes us out, and that is just the way it is.
