Why are doctors so useless sometimes

Good luck with the endo. I hope you get some answers and reassurance.

Well he sounds difficult, but he sent you to the endo, so the final result was good, much better for you than just send you for a fasting blood test.

Sorry what is endo?

It's short for endochronologist
From wikipedia:
Endocrinology is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions called hormones, the integration of developmental events such as proliferation, growth, and differentiation.

The good news is that you have been referred to an endo. If you have high BS readings then your GP should have tested you and defined you as a diabetic if necessary regardless of you having the meter or not. I wouldn't worry about the insulin resistance aspect too much. Some of us Type 2s i.e. around 15% are not overweight and hence may show no evidence of insulin resistance unless tested for it. The treatment however, if tablets are needed, may be similar although less towards metformin and more towards the insulin stimulants and possibly both. Hopefully your endo will do all the right things and having a meter is a good things so you can check what foods are affecting your BS.
