Welcome to the forum, it sounds as if it was a bit of a shock to get your diagnosis but it can sometimes be a relief as it explains symptoms you may have been having.
For Type 2 it would be unusual to start straight away with insulin and other strategies would be suggested first. With an HbA1C of 99 it would be likely that you will prescribed metformin and advised to make some dietary changes as the first thing.
Many have been able to manage to reduce their HbA1C by adopting a low carbohydrate dietary regime and oral medication from higher levels than yours, it would only be if that was unsuccessful that insulin would be considered.
