I'm sorry you are going through this. I don't have a dog with diabetes, but hopefully somebody will come along who can help you.
I do have a dog with addison's and once in a while I will give her her shot and I hate it, have to give it in the muscle. Normally I will just take her to the vet to get it.
I was wondering about your vet saying your dog will go blind. I know it happens in people, but seems like that is only if they don't take proper care of themselves, don't eat well or take their medication.

Welcome to YT and hope you find the help you need!
