Have you read the newer approach to your diet to lower blood sugar naturally? I have read a couple of articles and purchased a book with new recommendations. I can't do the recommended exercises but I can do some of the food changes which help a lot. I never have relied on meds for my diabetes issues and have learned to avoid certain foods permanently which has been a big help. I also eat a high fiber diet and have little stress in my life at this time. Also I have studied depression and have learned to change my thinking to a more positive mode and be grateful for my little successes. I would not take meds for depression, but I would change my life and the people in it if necessary to have better health. I believe in eating new foods and there are lists on the web that recommend the best and safest foods for your particular needs. I can't do the very low carb diets out there, but I can count carbs very well and be satisfied to limit them.
Temporarily, I would accept some insulin shots as I did in the hospital some years ago when the pain medication raised my blood sugar.
When I came home, I quit the pain meds and the numbers came back down to prediabetic levels. I firmly believe in eating a low carb diet regardless of what the family or anyone else says, and searching for new foods that help you feel satisfied. It works for me. Dorisena

@jeannetta, I agree with @susu2. There are so many things going on, especially these past 6 months due to COVID. It sounds like your problems started even before that due to drug shortages and no longer having access to medication that was working for you and then the long journey of trial and error to find another medication. I can understand that would make you feel despondent.

Are you reluctant or concerned about using insulin?

Have you talked with a diabetes educator? Or perhaps asked for a consult with a dietitian who specializes in diabetes? They may have some non-medicinal approaches that could help.
