You do what works for you but I feel a little protective:

In a nice way, tell her to knock it off.

Your A1C was good and the only reason you are talking about diabetes is
because it is part of your anxiety and as far as your MD is concerned you
are doing well.

The therapist can help you with the anxiety over it -- not with the
actual diabetes itself because
your diabetes is under control



Ask her why is she so concerned about your diabetes?
Is it personal for her?????
By the way, very few people need to give themselves injections ---
she almost sounds crazy about this.
