You are not chicken. It is much better to go in understanding risks, thinking about them and what you would do should you come across a dangerous situation.
First I would say you should know the area you are hunting and be familiar with the terrain, especially because you (we) walk in the dark. Falling off a hill or cliff can be just as dangerous as a couple coyotes. Where I hunt (and I usually hunt alone), there are of course skunks and raccoons, but also some wild pack dogs and coyotes, so I do carry a handgun (I have a conceal carry permit) and everytime I get out of my truck, get my gear ready and start my walk to my stand, I try to make sure my right hand is free (to reach for the gun) just in case I do run into something. It is usually dark, but I have the lights in my cap and I will turn them on and off as I approach certain points in my walk. Being prepared is important and if you are thinking about it, then your senses are more in tune to what is happening around you. I make sure my ears are not covered when I am walking to my stand. I want to hear every sound. I love to hunt and understand the risks. Now it's not to say if I were in an area known to have wolves or bears, that I might not be a little chicken to go out on my own to hunt. I might actually think twice about it.
Enjoy your hunting but be aware of your surroundings. I am not sure what else you can do or have with you to protect yourself, but I am sure there are others on this forum that may have an idea that would be deemed legal.
