This is extraordinary to me! Some of these stories of lackadaisical care for diabetes sufferers are bizarre, given it's a progressive disease. Are you in the UK?
Hypos and hypers can be very dangerous - what are your particular symptoms? Have you had a blackout and if so have you told your GP/ doctor?
I was diagnosed in a London teaching hospital three weeks ago after a fall down an escalator. I was knocked unconscious and they cut all my clothes off.... I was lamenting this to the Snr Nurse on the trauma ward, saying I'd only started wearing those favourite things again after 25 years, following massive weight loss... and given I'd had a fall/ blackout her alarm bells began to ring and - she decided to test my glucose levels. That was about 9.30am...
Cue the entire hospital diabetes team on my case! - I didn't have a spare minute all day, what with the Diabetes Nurse (several visits); hourly testing; an IV drip as I was so dehyrated; the occupational therapist showing me how to test etc; and the nutritionist giving me lengthy advice after finding out what I usually eat.
They were all very thorough, and faxed through a long prescription and all kinds of info to my GP Practice in Suffolk... When I got back I was given an appt with the practice's Diabetes Nurse within a week, and spent an hour with her on Monday - I'm seeing her again next Monday.
It sounds to me as though you should be more insistent on getting treatment - and you certainly need to be testing yourself daily!
