Hi Miss Vampyr (might I ask you to explain the screen name?),
I had a customer and friend who moved from Bloomington, IN to Helena, MT quite a few years back. I've seen photos, and it is very scenic there... probably a very nice place to live. I've had most of the same complications as you (that is, neuropathy and retinapathy), and like you, I had open heart surgery. (Ten years ago I had a quintuple bypass. I've also had vitrectomy surgery in both eyes.) Unfortunately, back in the days when I was diagnosed they hadn't established a connection between control and complications yet. Blood glucose meters hadn't come out yet either.
I do believe that it is never too late to benefit by tight control. Further damage can definitely be prevented or at least, reduced by a combination of diet, exercise and proper insulin dosing. When I was diagnosed in late 1970, I was told for the first time (of many times) that I had to stay healthy in order to "stick around" for the cure. Well..., I'm still waiting 40 years later, but, nevertheless, I believe that's good advice. Juvenation is not only a great source of ideas, but it's also the best place for the support and encouragement we all need at times.
If you haven't read Dr. Richard Bernstein's book, called "Diabetes Solution," I highly recommend you do. Even if you only follow just a few of his numerous "radical" suggestions (his diet is tough), the book offers hope, especially with regard to reversing or minimizing complications. Dr. Bernstein himself has had Type 1 Diabetes for over 60 years.
