I think the more time you spend in the woods, you get to see, feel, and understand how the woods works, understanding what's going on around us leads to comfort and a sense of feeling of safe. Anxiety is most likely the culprit here. So spend more time in the woods, try camping in a place you trust could even be a state park campground, hike by yourself in local areas you know, you can build on safe fun successful experiences. Oh yeah a good sleeping pad helps to.
