Welcome to the forum

Sorry to hear you are having to balance multiple conditions, which don’t always play nicely together.
Which medications are you taking? And are any of them intended to help with your blood glucose management.
Perhaps one way to start would be to get a BG meter (your GP surgery may be reluctant to provide one), and to start with a gall-bladder-friendly diet, then use the meter to see which of those choices cause the least blood glucose disruption.
People can respond to the same foods quite differently, so it can be quite difficult to judge things just based on their reputation, as your own response may not match that!
The most cost effective meters members here have found are the the
SD Gluco Navii or the
Spirit Tee2 which have pots of strips at around £7 for 50 (some other brands would set you back £25!).
You can take a reading just before eating, and again 2hrs later. Ideally you’d want your glucose to have risen 2-3mmol/L or less by that time. Even if your numbers are a bit higher than you'd like at the start, if you keep the ‘meal rises’ small, your overall levels should start to come down gently.
Not sure if
@eggyg will be able to suggest any foods that work for both gall bladder and diabetes?
