Hi and welcome to the forum !
Do you have a hospital DSN you can talk to about sorting things out ? Do you attend a hospital clinic ? The Libre is not a magic answer to all our problems, though it can certainly help.
Do you know why your Hba1c is at that level ?
Edited to add : Sorry for all the questions. You are obviously pretty fed-up with the situation and must be feeling anxious too. I think everybody on here will understand that. More information from you will help people to suggest what you could do about this.
