That's quite early for a T2 to progress to insulin. I agree with
@Fenn that you should see if you have been overlooked but it may also be worth asking for the T1/T2 tests as an early progression to insulin is a red flag for T1. You'd be on insulin either way but T1s generally get access to slightly better treatment and technologies than T2s. I can't help with local groups, but there are a number of courses (some online) to help T1s cope with insulin dosing, which might be useful to you.
Can I ask what kind of insulin you are taking? Are you on a fixed dose regime or do you have freedom to adjust your insulin to your food?
