The feelings you are having are normal. You have been diagnosed with a condition that will change your life. You may find that you will go through stages of different emotions, fear, anger, guilt and self pity. This is all normal and eventually the feeling of acceptance kicks in. I felt a kind of grief for my pre diagnosis life but once I had accepted it then I felt I could move forward.
Well done on your bg control, keep up the good work. Remember that improving your health is an empowering thing, you can be in control of your future. Good luck.
