Hi SFJ and welcome to the A/P!
I too am so sorry to hear about your negative experience with your current doctor.
If I may also ask a couple of questions, in order to best advise you with the best suggestions.
1) Is your doctor a GP or an endocrinologist?
2) I am assuming you are talking about type 2 diabetes?
3) Have you been able to lower your BGL's/A1C with diet and exercise alone, or are these exceeding healthy levels in spite of your efforts?
My husband is type 1...and I of course deal with anxiety...so I may be able to help you out a bit if you can give me just a bit more information! :)
Talk to you soon,
S.C.
