Waiting can be such hell and the urgency behind this can be absolutely crushing.
What Erica said is absolutely right on. I wouldn't think of the Edmonton doctors as a wall (their wait list is another story). The term Gatekeeper couldn't be further from the truth. From my experience with one (and hearing about the other), they are more facilitators. They do take you at your word and will provide you with what you need in terms of referrals or letters.
As for the referral to the Calgary endocrinologist, there are GP's in Calgary who will prescribe HRT. All is not lost yet.

You can PM me as well if you want to talk. Otherwise, I hope to see you at Friday's meeting.
