Hello, your numbers are higher than they should be for sure.
Maybe time to see your doctor and get a hba1c done.
Depending on those results, likely higher than normal, you will be officially diagnosed.
Irrespective, assuming type 2 diabetes, the treatment will be losing weight if overweight, cutting carbs (particularly sugar, grains, starches - look into low carb / ketogenic diet), exercise, and medications if the previous lifestyle approaches are not sufficient.
You can do this.
