Honestly, some of your symptoms sound like non-diabetic hypoglycemia. I only say this because I have a few friends with the condition and they describe a lot of the mild low blood sugar symptoms that you've described. Non-diabetic hypoglycemia, from what I understand, is a very mild condition where you just need to make sure you eat frequent small meals - if you go without food for too long you start to get shaky, nauseous, even numb lips. I thought numb lips and mouth was strictly an insulin-induced low blood sugar symptom until my husband told me he gets that all the time when he forgets to eat - he has a genetic liver condition, which sometimes is associated with hypoglycemia since it prevents the liver from functioning properly and releasing a steady stream of glucose.
Anyway, if you're concerned, it's very easy to get a cheap glucose meter from the pharmacy. Test your blood sugar when you don't feel well and see what the deal is. Why not? If it's a low number, bring it up with your endo.
I'm not very familiar with thyroid issues; all I know is type 1 diabetes, and your blood work does not seem to represent that diagnosis at all. For reference, my a1c was 10 when diagnosed and in DKA.
As a side note, I'm sorry that your endo felt it was a good idea to say "I betcha have type 1" and then send you on your merry way. That's not cool.
