Welcome to the forum
@MitMot
Sorry to hear about your diagnosis. Be kind to yourself, it can come as a bit of a shock and take some time to adjust.
Diabetes is a serious condition, but it’s also one that can usually be managed well with a few changes and adaptations - and it shouldn’t stop you doing things you enjoy. Try not to be disheartened, many people on the forum later reflect that their diagnosis became a catalyst which prompted them to make positive changes towards a healthier and more active life.
As others have said, you can use a BG meter, taking a reading before and 2 hrs after eating to see how food is affecting you as an individual (everyone is different, and it’s important to understand your own tolerances and ‘safe choices’). The numbers themselves sprint matter so much at the beginning, it is the difference between them - the ‘meal rise‘ which you want to keep as near to 2-3mmol/L as you can. If you happen to identify any carbs that seem to be spiking BG, you can experimenting with reducing amounts or swapping types (sometimes just having things at a different time of day makes a difference).
If you are interested in this apporach you may find
test-review-adjust by Alan S a helpful framework.
If you’d like to try this approach and have to fund your own meter, a key factor is the ongoing cost of the stips - One of the most affordable meters members here have found is from SD, and has been recently updated to the
SD Gluco Navii which has
test strips at around £8 for 50

Maggie Davey’s Letter and
Gretchen Becker’s book, as very helpful starting points.
Good luck, and keep asking questions
