Go get yourself checked out. Book in to see the nurse at your GP's, ask for a finger prick blood test. Short, sharp but ultimately painless. You won't even see a needle, let alone feel it for more than a fifth of a second. You can only find your blood glucose level (i.e. a diabetes check) through a blood test of any sorts - this is the easiest and most painless way. Get it done and let us know how you get on. If you really do have the symptoms you need to go TOMORROW. All the best.

PS Edit - if you do have diabetes, the injections are known as subcutaneous - into the fat of your arm, arse or legs. You do not need to inject into a vein, and as ascience says, they are painless 99% of the time. And they keep you breathing too... ;)
