Camping by myself - Small girl

I want to go camping and I want to go by myself. My coworkers and a few friends have encouraged me to go saying that I will be fine because not only am I prepared (bear spray, a loud air horn, and some other things) but I am camping with 3 dogs. While they are not fighters and will not attack, two of them do bark, especially at strangers at night (they still do it at the dog park). They are bigger, a husky, a Belgian malinois / Husky mix, and a border collie Australian Shepherd mix. I am camping in a campground but my spot is a little more secluded.

I am just a little nervous. I really want to go by myself, get away from everything and everyone, and reset. But I would like to be safe.

I reserved the camping site for two (so that if I have to say it in front of anyone, they will think an additional person is joining. I will be bringing another chair (so that anyone walking by will see two chairs). Does anyone else have any tips for me or things I could do to prepare? I do know that if I am really nervous I can sleep in my car, just wanted to see if anyone had any advice!
