Hi,
@EmmaJ99 , I agree with
@Alison54321 .
You're recently dx'd so they'll not give you a row or anything like that.
It's their job to give you steers on how to adjust food and insulin.
They'll probably just say, ok, you're having hypos, lets think about ways of adjusting insulin amounts.
You're recently dx'd so there's probably a bit of honeymoon period going on - your beta cells in your pancreas which make insulin have had a bit of rest through you taking insulin, so they start making insulin again, but don't tell you, which throws calculations out. That'll wear off eventually.
Getting basal insulin amounts right is the main thing to look at. If your basal isn't right, it's a house built on sand. Basal is meant to keep you steady when not eating. Too high, you'll be snacking to keep levels up. Too low, you'll be doing fast acting to lower it. There's some tips on checking basal here:

Don't know how much reading you've done, but a recommended book is Think Like a Pancreas by Gary Scheiner.
A mistake which health care professionals often make is looking at it just in terms of amount of carbs and amount of insulin. It's more complicated than that. There's the time aspect too. Fast acting insulin like novorapid takes about 20 mins to start working, fiasp is shorter, they reach a peak at about an hour or so, tail off after that for about 3 to 5 hours. The trick is being able to match those time patterns to the digestion rates of different types of food.
Scheiner's book will give you some tips on that, as will Sugar Surfing by Stephen Ponder.
You ask about treating hypos. Every one of us has overtreated hypos. It's probably the right thing to do in the early days to avoid any nasty situations. After a while, though, it's true that a modest 10 to 15 grams us enough to pull you out. Wait until you're having a mild, slow drop hypo and experiment with just 1 or 2 dextrotabs. You might be surprised by how much that tiny amount of glucose will raise you.
