Robert, have you considered a pump and CGM? Sounds like control is your biggest problem, but I'm only going on what you have posted here (I'm very new, so don't know you from other posts).
My own story... diagnosed 15 years ago type 2. For (pretty heavy) personal reasons, I fell off the wagon two years ago, and my diabetes gradually deteriorated until I almost crashed beginning of June, sugars well into the 4-500 range, chronically.
Went on insulin, and with gusto. I've been injecting 6-10x a day, testing almost as many, with the goal of tighter than ADA "tight guidelines" tight control. I'm there -- my BG stays 80-100, with post-meal peaks not exceeding 140 (usually not even 130).
And I have pretty strong insulin resistance.
All that said, here'w what happened: All neuropathy has vanished (through a painful, pins and needles transition, as the nerves came back on line). Blood pressure has dropped from 170/115 to 118/78 (yesterday). Head is clear. Have lots of energy. Emotionally upbeat. Excellent appetite again, enjoy food! No more vomiting 1-2x a week. And on and on.
Because of this, I've started the process to become a cyborg with a pod and dex g4 sensor grafted on to my body. I love feeling this way. I love the control. I love the prospect of keeping my kidneys and eyesight.
So, don't know what your situation is in detail, but it really sounds like you need a much more precise and responsive treatment regimen. Cost may be an issue that I'm not accounting for here. If it is, though, you can achieve the same level of excellent control with pens (I'm doing it) -- but it does take considerable effort.
It's worth it, though.
