You say you've been unwell but have you any other symptoms that sometimes (but NOT always) accompany diabetes? E.g blurred vision, increased thirst, needing to keep getting up in the night to have a pee, a fuzzy head ('brain fog'), bouts of dizziness and feeling hot and sweaty (for no good reason you can see), tiredness, pain or tingling in the hands and feet (neuropathy).
If not, there's a chance you haven't got diabetes, and I'll keep my fingers crossed for you. But, as others have pointed out, only further blood tests and your GP can tell you for sure.
Good luck.
