Welcome to the forum

Sorry to hear about your double diagnosis. What a kerfuffle to have just got your head around one thing, then to be landed with another!
But we have several members who successfully balance multiple conditions - so hopefully you will be able to balance and juggle the requirements of both.
Perhaps it would help you to simply check your Coeliac-friendly menu to observe the impact on your BG levels, and make adjustments from there?
You can use a BG meter, taking a reading before and again 2hrs after eating, to see what the differences are to identify any carbs that seem to be spiking your BG. Ideally you would want to see a ‘meal rise’ of no more than 2-3mmol/L at the 2hr mark. Once you can see how you respond to different meals you can begin experimenting with reducing portion sizes of the carbs where you see bigger rises. You might find that you are particularly sensitive to carbohydrate from one gluten-free source (eg potatoes), but have more liberty with others (eg basmati rice) - It’s all very individual! You might even find that just having things at a different time of day makes a difference - with breakfast time being the trickiest.
But with a little experimentation, hopefully you can find a way of eating that is varied and enjoyable enough to be usable long-term, while also being helpful in the management of both your conditions.
If you need to self fund your BG meter, the most affordable meters members here have found are the
SD Gluco Navii or the
Spirit Tee2 - which both have test strips at around £8 for 50
