Rather than condolences, congratulations and welcome! You're now part of a very exclusive club! (Whether you want to be or not lol!)
It's a big shock being diagnosed, and the questions come thick and fast but the best piece of advice I can off is that you acceptbis as part of you, but don't let it define you.
Diabetes is a rollercoaster and you have bigs highs and lows, both I sugar levels and moods - when you feel lonely and overwhelmed, reach out, have a rant, stamp your feet and when you have good news and success, share and inspire.
I wish you the best of luck on this journey and a happy and healthy life ahead.
