Please do let them know of your issues and see what they might have to offer you. Some areas have an online option for their Desmond course, but not everywhere.
Another alternative, is the Low Carb Programme on this website can now be given to T2s on prescription. That is a 10-week programme, focusing on improving your diabetes, using diet, with lots and lots of educational content videos and the like. That could work really well for you as you can do it in your own time, at home, if that's what suits you best.
Why ot contact Desmond, and if they can't help, then ask about the Low Carb Programme from here:
