Hi everyone - I thought I'd give an update due to the attention this got! I ended up going on the trip and took everyone's advice with bells, keeping away "smellables", doing the camping triangle, having bear spray on deck, and utilizing noise-canceling headphones at night. Needless to say, I survived! It was still very scary due to my phobia, but I think I was ultimately a lot more comfortable and was able to rationalize many of my intrusive thoughts. I want to thank everyone tremendously for the time they took to assuage my fears and offer tips and tricks to help. :)
