Hello ANG18 and welcome to the Forum
Being diagnosed with T2D (type 2 diabetes) is a shock, and you are quite OK to feel overwhelmed, emotional, and to cry
So have a good cry, then get down to the business of dealing with the situation
There is good news and bad news -
Don't be frightened by any tales or horror stories you might have heard; it is perfectly possible to live well and healthily, and without any of the nasty side effects or complications you might have heard of
However, to achieve this you will almost certainly have to change your diet, and possibly other aspects of the way you live as well -- but fear not! it will be different, but not impossible, as many of the Forum members have shown
Diabetes is the inability of the body to process carbohydrates properly, with the result that glucose builds up in the blood, and it is this accumulation that causes the problems we call diabetes
The accumulation is treated by medication, and changing the diet by reducing your carb intake - if you take in less, there is less to end up in the blood
It is important to realise that as well as the obviously sweet things like cakes, biscuits & sugary drinks, carbohydrate incudes starchy things like potatoes, cereals, bread, pasta, & rice, so you must reduce the consumption of all carbs
This is difficult at first, but you gradually adapt to a new way of eating - and living as well, as many people take the diagnosis of Diabetes to cut down on things like processed & junk food, cut out smoking and a lot of booze, get more exercise, lose weight, and all the rest of the healthy stuff you hear about - and feel better for it.
No-one knows exactly why, but many people with diabetes have a feeling of depression, worry, anxiety, looking over their shoulder, and so on ..... and being emotional!
So you may well find that as your diabetes is controlled you start to feel better from that point of view
I suggest you read through previous Threads & Posts in the Newcomers, Food & Carbs, and Weight Loss (if necessary) Sections, and take it from there

Oh, and I nearly forgot - we've all been where you are, so feel free to ask questions; don't be embarrassed, nothing is too silly!
