Concerned and a wee bit scared.....

Hi.... I've posted before but I was treated for T2 back at the start, I've since had very high hba1c at 86, 94 and 98. Had another blood test done to look at "what type of diabetes I have" looking for markers in antibodies????? Anyways, long story short, I WS started on insulin regime, (after years of a cocktail of oral tablets were unsuccessful- I'm currently on 18units x3daily of novarapid and 26 units of lantus) .... So.... Conversation with nurse specialist a couple of days back, and she suggested the following "I see that you have an appointment with the consultant soon, I'd like you to ask him to explain the TYPE OF DIABETES you have, as your markers were just on the border, but your insulin in reserve was,..... Well, it was...... Anyway, yiu need to speak to the consultant, it's not going to change anything, you're still going to need insulin ". Now is it just me, or did that message appear to be telling me something that I have clearly missed?? I was told I WS T2 for years, told to take these array of pills, vomited and felt ill for months, but" percevered ". I then got told I was late onset T1, started insulin, stopped all oral tablets, now I'm hearing that the type I was told may not be right?.... My BG is not responding as well as I would expect from insulin regime. For example my BG yesterday at 4pm before food was 23. 7. I average between 19 and 26 and have done for 2years. I keep away from the bad stuff (carbs) and I keep a strict food log. My life evolves around this bloody BG situation. I'm still very very tired, blurry vision, and bruised tummy.... Basically I'm having a blooming yukky time. (sorry for the rant). Why would I have to speak to my Dr about Antibodies?? What did she mean about markers? And why can't I get my BG below 15 let alone 10?

Thanks for your reply. I'll reply in more detail after work.
