Hi. As you say you are slim, I would ask for the two tests for LADA (Late onset T1). The tests are GAD for antibodies and C-Peptide which measure your insulin levels and helps to place you in the right category. Many GPs are pretty ignorant about late onset T1 and you need to suggest the tests to them. If your pancreas is failing there will be a honeymoon period during which the need for meds will increase. I may be wrong, of course, but worth knowing what many of us have been thru. If your GP is like mine and refused to accept that I wasn't T2 and kept piling on the tablets with no effect, you can have these tests done privately if needed. In the meantime keep the carbs down and keep testing.
