After receiving my proper reprimand from my endo about her protocol for filing a complaint regarding my care, there seems to be some good news. I did get a call from the D-center. Matters were looked into and although I know some of the information given to me about the pump training I attended was inaccurate, an apology was given (from someone higher up) and I was offered to attend the correct training session. So contrary to my endo's belief, mistakes were made, whether or not she is willing to admit them is another issue.
But I must admit, part of me still wants to send my endo a follow-up letter( and I still may). Physicians should be held accountable not only to how they treat their patients medically, but also in how they speak with them as a human being. Their failures are not mine and will not be made mine. Perhaps I should say my "former" endo's failures are not mine.
