It really does sound like you have been given very poor (and possibly dangerous) advice. Your symptoms do sound like T1, but don't take my (or anyone else's) word for it. The only way that you can tell the difference between T1 and T2 in the early stages is with a test that measures your "C-Peptide" levels (they are normal or high in T2, but very low or even zero in T1). If you haven't had this test, then your doctor is just guessing. This is a potentially dangerous guess, because if you are indeed a T1 then it is possible that without the correct treatment you will go downhill very quickly. As others have said, if you seem to be getting worse - particularly if you get nausea or stomach pains - then get to a hospital fast.
Assuming that doesn't happen, then next time you see your doctor (or a diabetic nurse) then press them about why they think that you are a T2. Many GPs don't know a lot about diabetes, so unless you are absolutely confident in him then you should ask (or demand if necessary) to be referred to a specialist. Whatever sort of diabetes you have, then the advice to cut back on carbs is good. If you are a T2, then that (and increasing exercise) might be able to control it effectively, or if it doesn't then there are various very effective drugs. However, if you are T1 then you will need insulin very soon. That isn't anything to be afraid of - with modern equipment the injections aren't painful - it just adds an extra chore to your life. Without insulin, though, a T1 will rapidly get very sick and won't survive for long. This is why it is vitally important to get the diagnosis right!
The advice about not testing is, sadly, fairly standard for T2s these days. If your doctor tells you to test, then he will have to prescribe strips and they are expensive. Many PCTs seem to be strongly discouraging doctors from prescribing strips to newly diagnosed T2s. However, without testing it is much harder to monitor your condition and impossible to learn what effects various foods are having upon your blood glucose. You should test regularly, and learn how to interpret the results. If in doubt, post here - lots of people will help you to do this.
