High blood sugars

I have been diabetic for the last few years, on occasion I have been ill and therefore had raised blood sugars but usually I can get rid of them with increased doses of insulin. For most meals I have 8units of apidra, however the last week I have been increasing the units more each time, sometimes double, and I can't seem to get it below 10. (My usual is under 10). I have had a small amount of ketones which I know is not dangerous yet after the continuous days with them I have begun to feel awful. I work in a hospital and was sent home on Saturday and had yesterday off, I have tried to contact my gp but have been told a diabetic nurse will not be available to call me until tomorrow at the earliest.
When I was diagnosed I was let down massively by my doctor therefore sometimes wish for extra reassurance when my diabetes misbehaves. But I was wondering if anyone has any other ideas with who to talk to just for advice on how else to go about it!

Sorry for the essay thank you
