The real issue is anxiety

Today as I was watching television I have come to realize that the problem is not fear but purely anxiety.  I am anxious as to what will happen.  I feel like a little kid who is not to just grow up or to learn things.  I am not fearful, but the anxiety and the doubt is what are really the problems.  I would like to overcome this but I don't know how.  I would also like to stop all of the doubting and the second guessing, but that is even harder to overcome.  I wish I knew where to begin.  But I have to realize that in the grand scheme of things, I have nothing to be anxious about.
