Hi and welcome. Pleased you decided to delurk as posting helps to keep you focused and accountable.... and there is no need to be afraid, we don't bite 🙄
What I find is that I now need much less food, but I think it takes time for your stomach to shrink after being used to eating such large carb rich meals. The odd occasion when I have eaten out in the last couple of years I have not been able to manage nearly as much as I used to eat and I must learn to stop sooner..... Chinese buffets for special birthday celebrations have really left me feeling horribly ill afterwards as you don't realise how much you are eating until you suddenly feel "stuffed".
One of the key things for making low carb sustainable long term for me was increasing fat intake. I keep plenty of high protein and fat snacks foods that I can eat if I feel hungry. Things like lots of lovely cheese, salami, olives, nuts, little feta stuffed peppadew peppers, boiled eggs which I have with a teaspoon of full fat mayonnaise, plenty of salad and full fat (or ideally, cheese) coleslaw, veggie sticks like cucumber, peppers and celery with sour cream and chive dip (proper chilled counter stuff not the Doritos type jars), which is also really nice with some microwaved broccoli. My not so guilty pleasure is a packet of pork scratchings (all protein and fat and no carbs) and not forgetting a half a square of 85% dark choc with a teaspoon of crunchy peanut butter.
Of course if you are wanting to lose weight, then you need to keep the fat intake reasonable, but do go for full fat versions of natural yoghurt, milk and mayonnaise and coleslaw. The fat will slow down the release of any carbs you eat with it but more importantly it will help to stop you from feeling hungry and will provide slow release energy. Fat is rich and calorie dense so you don't need much to help you feel full/sated and as I said, once your body gets used to this way of eating without all the bulk of carbs, your stomach shrinks and you don't miss those big plates of food you used to eat.
You may find a fibre supplement helpful in keeping your digestive system moving comfortably, as many people experience constipation when they change to low carb, particularly if they were eating a lot of wholemeal bread etc prior to the switch. I now use a fibre drink on a morning made with psyllium husk and chia seeds which creates a bulk of soluble fibre gel which passes through my digestive tract very smoothly and keeps me very comfortably "regular". These are not laxatives so they don't cause your system to spasm or anything, just a bulk of soluble fibre which kind of gently clears the system each day. It works brilliantly for me and I wouldn't be without it.
Anyway, it sounds like you are doing all the right things so best of luck with your diabetes journey and I am sure you will see an impressive reduction in HbA1c at your next check as a result of the changes you have made.
