“What they think” is not a confidence-inspiring diagnosis. You may indeed be Type 2, but there is a strong bias, particularly among PCPs, to diagnose Type 2 simply based on age and without performing definitive tests. From your description, it sounds as though that may be your situation. Misdiagnosis of adult Type 1s is a significant problem. See this link.
Before a realistic treatment regime can be developed, you need to have as definite a diagnosis as possible. From what you posted here, it sounds like you and your medical team are still shooting in the dark, so to speak. You should require them to perform the tests for T1, if only to rule it out.
