I don't understand how the replies you've been getting are negative. If I was worried that I had a serious, life-altering, potentially life-threatening condition and I had test results that came back normal, had a doctor who reassured me I didn't have that condition, and went on a forum and got 40-50 replies from people with that condition saying that their experiences weren't similar to mine, I would be extremely relieved!
Trust me, Type 1 diabetes (or any diabetes) is not something you want, and so it's great that all of your test results (fasting of 92, normal insulin, no antibodies) point away from diabetes rather than towards it. What you are concerned about as a high fasting blood sugar of 105 or 107 are fasting blood sugars that most of us would love to have for the rest of our lives.
Having diabetes does not make life easier. Your numbers don't suddenly become normal once you have a diagnosis. Even with a strict diet, strict medication, strict monitoring, strict exercise regimen, and putting in maximum effort, control does not come easily at all, even for those of us using the latest technology like insulin pumps and continuous glucose monitors. For us, "control" does not mean normal blood sugar levels, it just means blood sugars that aren't constantly bouncing from dangerously high to dangerously low. Diabetes affects every single aspect of life, blood sugar being weighed into many daily decisions, control being half science and half guesswork. It takes constant vigilance, constant monitoring, constant adjustment. You wake up each day and go to sleep each night knowing that, if the highs and lows you experience daily go too far in either direction, you could be facing life-threatening consequences at any time. You worry that, despite all these efforts, you may still end up with a serious complication down the road. The disease affects not only you but your entire family and close friends. You lose sponteneity. There are no vacations from the daily grind. It is a hard disease to have, a disease no one here would ever wish on someone else.
I would be clear to your doctor about how bad you've been feeling, and maybe seek a second opinion if your doctor brushes you off. But I wouldn't be surprised if another endocrinologist looks at your numbers and says the same thing that this first one has. If that's the case, you should be happy!! Thyroid disorders can be very hard to control and can make you feel horrible, so I would get a doctor who's willing to be more aggressive in trying to treat that, as it could be the source of how you've been feeling and your blood sugar levels. If you are worried that your blood sugar readings are a bit too high, then make sure you're doing things daily that will keep them lower (and are healthy anyway) like eating regular meals that are lower in carbohydrates, exercising 30-60 minutes every day, reducing stress, sleeping well, and getting checked yearly.
