The test is to detect the amount of glycated haemoglobin in your blood. Higher blood glucose levels results in more glycated corpuscles. The level at which diabetes is diagnosed is 48, above that level indicates that your glucose levels have been higher than considered safe during the last three months - the lifetime of a corpuscle.
Many of us have higher numbers than that on diagnosis including me ( 92) when I reached 64 it was a real milestone!
I am sure you can bring it down from there . Great news that you are still succeeding two weeks in . Frankly kids often have no idea of what they are saying or the hurt they cause so stick that to one side and focus on yourself !
