Tom, take heart.  Institutions have their place in this world as without them anarchy would reign.  They never do and never can live up to the ideals we have for them.  I encourage you to take solace in the example of Jesus.  You'll note that he didn't take a lot of time defending the institutions of his day, or, following with any rigor the doctrines of the faith of his upbringing.  My suggestion is at once both easy and difficult to follow - simply be Christ to, and, receive Christ in, every single person you encounter each and every day and you will experience peace both in your heart and peace in your relationship with the current iteration of institution of the RCC.  All else is distraction.
