The uncertainty of the world has everyone on edge. Our nerves can only take so much. We all have been nervous about something or another. We have all waited for something we really wanted and we were not sure we were going to get it. Perhaps it was the results of a test that could determine a school grade or our quality of life. There is an element of fear in being nervous because it involved the unknown and a level of anxiety about where things are going to go in the future. Nervousness is a legit emotion and feeling at times it is something you have to feel and experience.
