Hello '1970'
Its all a bit confusing this diabetes isnt it, first thing i would say to you is please go back to your doctor and tell her all your symptoms, they may or may not be diabetes related.
and second, you need to learn about carbohydrates, these are bread, including white AND brown, potatoes, rice, pasta, starchy vegetables and fruit, these foods can give you spikes so you need to test to find out and then maybe either reduce the quantity or cut them out altogether. I suggest that you get yourself the Collins Gem carb counter book and you can work out the carb content of all the food and test how it is all affecting you.
Try and get hold of Dr Clarkes book, The Diabetes Revolution, it is easy to read/understand. I know you are frightened, but I can assure you it will all get easier with time, the more you learn the more confident you will become and you will not be so scared any more. Do not worry, you will get there, we all have to start somewhere, what you are experiencing is normal and there is so much information out there its overwhelming and you feel just a failure, well you are not, you are doing very well already by asking questions, so give yourself a pat on the back.
Just keep on asking and dont despair, you are not alone and everyone in here will do their best to help you along.
All the best
Karen
