The highest level of mastery is realizing how much you don't know and that nobody knows anything compared to what there is to know. Beyond the feeling of unease that comes from the above realization, who is the voice the back of your mind who is critical of your code or your technical decisions? Is it an old voice from childhood, a parent or a teacher, or is it current, your peers for example? These voices are sometimes triggered by events going on in your life, work related or not. Is it really your code or is it that you don't work in a supportive environment? Perhaps someone is gunning for your job and being subtly critical in ways that are getting to you. You might want to look at "egoless programming" and work on getting your ego out of your code and into the competitive workplace where it is more relevant.
