I'm with Mike, @Nico - you need to seek emergency care with those numbers, please do so - you can't wait until March. The nurse does not appear to understand the potential seriousness of your situation
Glad to hear you are feeling much better Nico 🙂 Do keep a very close eye on things though, and if you feel unwell again, do seek help straight away, especially if your levels go into the high teens or 20s again. Personally, I think you ought to be seeing the specialist much sooner, but you know how you feel, so know more than me! 🙂 Was the possibility of Type 1 brought up at all?
How do you feel generally @Nico? Did the doctor/nurse mention any ketone testing?
They should really have given you something so you can test at home
High and fluctuating levels will make you feel tired unfortunately
I'm sorry to keep banging on about it, but what did the nurse or doctor recommend you should be doing to get your levels down? Metformin will not do it and you shouldn't be left feeling scared to eat things. 
Yes Nico, there are tests they can do to distinguish between the two. Type 2 generally means that your body is producing insulin, but your body's cells can't use it very well, so your levels go high. Type 1, on the other hand means that your body isn't producing enough insulin so again, it can't use the energy from any food you eat and your levels go high. The big problem is that with Type 1 you don't have enough insulin to do lots of other things your body needs to do, such as clearing away ketones, which can also go high - if they get too high then you can fall very ill with something called DKA (Diabetic Ketoacidosis) which basically raises the acidity levels in your blood. If that happens (and it can happen quite suddenly, over a matter of hours) then it is a medical emergency
This is why we are so concerned, because we have read of so many members who have been misdiagnosed as Type 2 and then really had to struggle for far too long.
You're definitely a puzzle! 🙂
