Hi Alison Louise,
Sorry to hear you're having such a challenging time emotionally. Although it must have been a dreadful shock to receive a diagnosis of diabetes, as you will discover from the great people on this forum, it can be managed successfully.
Knowledge is power - try to learn as much as you can about the condition, and it may help you feel more in control of your life. Unfortunately high blood sugars, or fluctuating blood sugars can impact on your emotions - it could be that your emotional state is actually being influenced by your health at the moment too.
One step at a time, one meal at a time, one day at a time.
Sending you positive, empowering internet vibes,
Bx
