Hello
@Se2910 and welcome to the Forum and to the club that no one wants to join!
Sorry to hear about your diagnosis but, as they say in the movies, it is what it is, so let's think about what can be done for the future
No one knows exactly why, but people with diabetes often have a sort of depression, anxiety, a feeling that something isn't quite right, or looking over their shoulder but they don't know why
You will find lots of advice and encouragement about diet, weight loss, and exercise on here so follow it and gradually (but not too slowly we hope!) you will start to feel brighter, more lively, more positive, and more interested in looking after yourself .... a diabetic diet is actually a healthy diet that most people could follow - cut out carbs, stodge, sugar, processed & junk food, more veg, and all the rest of the healthy stuff we read about.
And this all has a sort of combined or rolling effect - the more you do, the more you can do, so the more you do, and so on
I've just re read your posts, especially #6 .... you can't turn the clock back, so dredge up some ancient hippy zen and follow the cliche that tomorrow is the first day of the rest of your life
Follow the advice on here about diet and do a bit of exercise, probably mostly indoors at the moment; you don't need a gym, there are loads of YT videos on indoor exercises
I do a sort of low carbohydrate Mediterranean diet ..... Tai chi in the morning; and Canadian Airforce exercises late afternoon and walk as I can
Treating & controlling diabetes will require acceptance, and changing the way you've been eating & living, perhaps for most of your life .... but the most important thing is not so much the change, rather making the decision to change .... after that, everything just falls into place.
Missing out carbs is strange at first, but you soon get used to it, and feel better for it
Look at Living With Diabetes on the Home Page of Diabetes UK, and previous Threads on this Forum, especially Newcomers, Food & Carbs, and any others you think will be useful.
Finally, please do ask any questions you might have, nothing is too silly or embarrassing on here, we've all been in a similar position.
