I feel very fortunate to have the medical team that I currently have - an endo and a primary care doc (internist) in the same clinic. Being in the same clinic, they work really well together and share information (which I've found is hard to make happen between doctors in different groups/clinics).
I was diagnosed initially (and incorrectly)by another doc as Type 2. I was 27 and not overweight, had all the classic symptoms of unquenchable thirst, constant urination, eating everything I could get my hands on and losing weight rapidly, and so tired I would lay my head on my desk at work unable to function. Yet my internist kept pushing the oral meds. I was literally begging for insulin.
Finally my gyno told me at my annual exam "you need to get to an endocrinologist fast, even if you have to mortgage your kids to do so" (really that's a quote, it's stuck with me all this time). I was young and I didn't even know endocrinology existed. But my gyno gave me the name of someone he knew from med school and off I went to the endo. About 25 years later, I'm still with the same doc, who correctly diagnosed me as Type 1.
What I like about my endo is that he listens, he doesn't rush me, he doesn't make me feel judged based on numbers or make me feel as though it's my fault when my efforts aren't successful. He's always available if I have an immediate problem. I feel lucky because he's really good at what he does - so much so that he now only accepts Type 1s as new patients. Most importantly, I feel like my medical team respects me - and I feel like as long term Type 1s, we've earned that - so I appreciate it.
One of the biggest problems that I see for Type 1s is the lack of endos or even primary care docs with experience in treating people on insulin, particularly in smaller communities. In my community, there is one clinic in town with a knowledgeable endo group - that's it. So if you "fire" your doctor, there aren't alot of other options anywhere in driving distance. I feel badly for those people who aren't in an area where they can find a doctor that they are comfortable with and don't have alot of choices.
