All of the above!!
I am no doctor, but I suspect the tingling is the start of nerve damage, this is your wake up call, your body telling you to take action or else. Diabetes is crafty and sly, it creeps up on you, for ages you feel fine, you are lulled into some sense of security then bang, wallop there you are with complications. You say you dont like doctors, so up to you to try and go it alone, exercise is a good idea, so is lowering your intake of carby/starchy foods, the important thing is that you test your bg levels, to try and stop progression you will need to take this seriously and try to keep to non-diabetic bg levels.
I have been seriously ill with complications following years of uncontrolled diabetes, it took me around 5 years to put things to right and even then I still have some slight issues and they may never ever go away.
You say that you enjoy cooking and baking, so do I, with a passion, but had to learn to rethink, I am very low carb, I have family, husband, 3 children, ,20, 19, 10, they are all carb aware, they dont low carb but are not overdoing it on carbs so for exampple we have a meal, they eat new potatoes as an accompaniment, I will have extra veg or salad. I make up pasta sauce, I eat it with zucchini noodles or shirataki noodles or shredded cabbage, sauteed in butter, seasoned, my family enjoy this as well, but recently had my nieces staying they experimented, they ended up mixing spaghetti with my shredded cabbage, result was a lower carb meal, too high for me of course, but they arent diabetic. Nobody can tell you how many carbs your body can tolerate, remember you want to stick to non-diabetic bg levels, but we dont know how much insulin resistance/pancreatic function you have, chances are that as you lose weight that things can improve.
As a vegetarian who enjoys cooking, get yourself a carb counting booklet from a good bookshop, fruit is best kept in small quantities as its high in fructose and our bodies recognise this as glucose, small quantities are ok, berries are best of all. Vegetables, generally those that grow above ground, root veg is too starchy, but as I have already said you need to find out your own levels.
Baking? Oh boy I love it, all low carb baking of course, have a good look at ewelina's blog to give you ideas, her lemon cake is to die for. There are plenty of low carb cake/muffin recipes online, just google for them, make your own sugar free icecream, there are recipes in the forum, using real cream, sweetener, none of the rubbish that goes into commercial ice cream and best of all your bg wont spike and its got to be better for the family too if they cut down on sugar.
Check out the low carb recipe section, make up aubergine lasagne, bake a low carb flat bread to go with it, mushroom risotto using cauliflower rice, now this is one meal that truly fools everyone who has ever tried it, people seriously think its rice, celeriac fritters, and so on, we arent vegetarian but we had mushroom fritters tonight, instead of thickening with bread we used oatbran, lovely served with a dip and side salad.
My family all enjoy the low carb italian pizza base, toppings are low carb anyway, my son made Scotch eggs the other day using a veggie sausages, covering in grated cheese and ground cashew nuts, or try a low carb quiche either no crust or you can make a nutty crust (recipes and pics here in the forum).
Finally before I stop waffling, we come to chocolate, you dont have to give it up, hell, no, just go to the Chocolate Paradise thread and you will find loads of chocolate based recipes that are actually good for you.
So, come on, wipe the sand from your eyes, life isnt so bad, be inventive, create some recipes yourself and post them.
A few links for you to explore with yet more ideas, two are educational, you need to learn about diabetes.
