Your General Practitioner denied you access to a chronic condition specialist even though you had asked and were obviously having issues?! I'd politely* ask him to read the NICE guidelines for T1Ds - the preferred method is to refer them to a diabetes specialist unit. It's now taken 'other problems' for him to refer you..............
*how politely you point out his inadequacies are entirely up to you!
I hope the Diabetes clinic can help make things a lot better for you come December.
