I totally agree with all the advice you have been given so far. Continue to drink plenty of low carb drinks. Water is best. How about sparkling water if you can't stand it plain? If you can go out for a walk or other exercise then this will help to bring your levels down
You do need to stop having high carb foods (maybe when your BGs are back to non-diabetic levels you will be able to add some back) . Vegetables (not root vegetables) and protein and fats are fine (not low fat products, instead choose real butter, cream, lard, olive oil etc.) These will help to fill you.
Here's some links to help you

Hopefully if you can low carb and exercise your numbers will start to fall very soon.
Keep monitoring your BGs throughout the day and keep asking questions. Don't forget the NHS Helpline 111 is there if you need it or if things get worse.
Good luck
