Hi Scarlet,
Yes. Been there, done that,got the T-shirt, unfortunately. It took them 4 years to realise I wasn't a Type 2. Quite possibly you will have LADA, which basically is Latent Autoimmune Diabetes in Adults...or late onset Type 1. I expect you'll get a GAD test now, that is a check on antibodies. It's not a test to worry about, as it'll be done like a normal routine blood test but it will help ascertain your Type. You may also have a c-peptide test to see if your beta cells are still working. I was told it was too late for me to have that test but possibly that test would be of benefit to you.
I think getting 'Type' wrong is more common than folk realise but I always joke that 'I like to be different'!!
Hope you get those tests you need. All the best, chocoholic.
