Hi steff, hope you get an appointment ok, don't take no for an answer!
Have you been prescribed ketone testing strips so you can test for them at home, if not make sure you ask for them and maybe take a urine sample along to the docs with you so they can test there and then. As some have suggested it's possible you may be type1. I was initially diagnosed as type 2, was told not to worry too much and not told anything about blood or ketone testing, that went on until I went back to uni and my files got tranferred there that I was suddenly called in to the hospital and put on insulin by which time I was far more ill that I needed to be.
Let us know how you get on.
