People who say "you're young" are speaking out of ignorance. The media loves scandals & headlines, & the obesity/diabetes timebomb headline is one that they trot out over & over again. I believe that this is the main reason why people think that diabetes is a disease of middle age & confined to those who are overweight. Most people don't know that there are two distinct diseases with different causes which present roughly the same symptoms.
However, I am very concerned about your description of your health. I'm not a doctor, just a fellow diabetic, but I remember the early days well. I was so poorly, I didn't know what was normal. I felt at the time that my GP failed me as he didn't treat my case as urgent & I had to wait two months for a hospital appointment. During that time, I couldn't get out of bed, slept through phone calls from work asking where I was, went to bed as soon as I go home from work, had to get up 15 times to go to the toilet though it was only a dribble each time (excuse the image, but it's important) before I'd get off to sleep as there was so much sugar in my urine my bladder was extremely irritated. I had to drink a pint of water every half hour to try & quench my thirst. I walked around like a zombie. My GP put me on tablets & then asked me how I felt. I used to say "OK", I thought everyone felt like that. Once I got insulin into me, I realised what life should be like.
I eventually went private & was admitted to hospital within a week. The doctor there told me that I'd have been in a coma before my NHS appointment came around. I now know that I had what's nown as DKA & is a very serious condition. I really, really don't want to scare you, you must be pretty scared already. But if you feel very poorly, get straight down to your GP again and tell him/her about every symptom. Tell them how hard it is to deal with every day tasks & make sure they test your blood glucose level with a finger prick test there & then (if possible, go first thing in the mornig and don't eat before you go). Better make an unnecessary visit than end up in an ambulance.
I small tip on diet, as a type 1, you would inject insulin before a meal to match the carbohydrate in that meal based upon the ratio agreed by you & your health team (e.g. I use 1 unit of insulin for every 12 grammes of carb eaten). If I have a no carb meal (e.g. tuna & lettuce or bacon & egg), I don't need to inject any insulin. Type 2s (I believe, though I don't know much about it) often have low carb diets which hekps their diabetic control. So, it might just help you a little while you're waiting for tests/treatment to cut out most of the carbohydrate from your diet or get rid of the sugary carbs & change the quick acting starches (baked potatoes, white rice, white bread) for slower acting carbohydrates such as brown rice, granary bread & pulses. (You mustn't cut it all out as your body needs some carbohydrate to operate properly.)
I will say again though, diabetes is a pain, but not the end of your life as you know it. You'll learn to deal with it. Good luck.
