I am so glad to hear that they finally reached a diagnosis.for you. I am not surprised you feel a lot better. Don't push yourself too hard at first. The feeling of having renewed energy is something most of us will recognise. It looks like they've put you on Levemir as your basal /background insulin, with Novorapid to cover the carbs in your meals. Best to keep them in different places to avoid taking the wrong one, when you're half asleep or in a hurry.
I hope that you were warned about hypos. Have you decided on sources of rapidly absorbed carbohydrare for use to rause your levels in an emergency ? In this situation, liquid carbs such as Coke (but not the diet variety) or orange juice are likely to work faster. Out of the house, I always carry glucose of some sort in pockets and in my bag but a lot of people swear by jelly babies. There's a lot to learn but you'll get there. Good luck and best wishes.
