That voice is you, so perhaps you should have an honest chat with yourself on where the inner conflict really is? What are you expectations of yourself and are they realistic? What could you do differently to make yourself more pleased? Try to make a plan and some actionable steps, and perhaps your asshole alter ego might start to be less critical... just shutting down the voice will not necessarily make the feeling go away, and it will probably find another way to resurface, and that one could be more damaging and harder to understand..
