Hi and welcome.
You're exactly where I was when diagnosed - just over the "automatic diagnosis" line. The good news is that a reduced carb diet can educe your blood glucose very quickly - it did for me.
You'll find if you read around on this forum that there are many different approaches to contolling your condition. You need to find the one that works for you - not only in terms of reducing BG levels, but also in whether it fits with you and your lifestyle. It might all seem very confusing at first - there is a lot of dubious information around on the internet, much of it coming from people with something to sell.
This link might be very helpful as a starter - it's written by a member of this forum:
There’s a few things you should know. 1. Practically all carbs turn to glucose once ingested , so not just straight sugars, but starches...

I would strongly recommend buying and using a glucometer. Tagging @rachix who has a list of currently available models.
The usual testing routine is to take a reading directly before you eat, and then two hours later. This is not to see "how high you go" - the high point will probably happen after 30 minutes to an hour. What it does show you is how well your insulin system dealt with what you ate. The idea is that your system should return you to a low level close to your starting point after two hours. So you're looking for a second reading that is no more than 2 mmol/l higher than the first reading: and isn't above 7.8. If not, then there were too many carbs in that meal for your system to comfortably handle at the moment. The idea is you build up a record of food and readings so you know what affects you and how, and can make informed decisions.
Unfortunately the current official dietary advice for everyone stresses basing all your meals around "starchy carbohydrates" - this is no good for me as carbohydrates are digested to glucose, which is where we T2s have the problem. So I don't eat cereals, rice, bread, root veg like potato, fruit, beer, and sugar. I find it easier to not eat any of something than to try to judge weights and portions - you'll need to find what works for you.
One of the things about this way of eating is that I haven't ever been hungry - I rarely eat breakfast and usually have one meal a day in the evening with maybe a bit of cheese or salami at lunchtime.
Best of luck - I found this forum to be a terrific source of advice and help - do not be afraid to ask questions. And there's no "right way" to do this, but there is "your way". As long as you find your way that works for you, you'll be OK.
