Hi Jerry! Welcome to TuDiabetes!
There are many people in this community with similar stories to yours. You should check out the LADA group.
I don't think that there would be any difference in your treatment from KNOWING that you are a LADA. But it might teach your doctor what to test for next time someone else has a similar case!
It would be good to get a c-peptide test, which indicates how much insulin your body in producing (perhaps you have already had this). That way you can see what happens to your natural insulin production over the years...
