How can you conquer white coat syndrome?

Ok Fluther friends,
So, I’m due any day now and I’m so excited – my only issue is that I’ve developed white coat syndrome from reading to much on-line.
My BP is great, it’s always 110/70 – once I calm down or at home, however, if my BP is high when I get admitted they wont let me use the birthing center – which is where I can have a natural birth with no drugs. ( what i want)
I’ve tried everything, deep breathing techniques, I laugh at myself because as soon as I enter my Dr’s office my heart starts pounding, I try and talk myself out of it, deep breathes, I have even written my body a note whilst waiting to try and calm down, but for the life of me – my heart wont stop racing, which of course makes my BP high.
I need to figure out a way to stop this madness in my mind that makes my heart race.
I’ve tried everything, meditation before going in, deep deep breathes – which work at home as I got it at home as well but I“ve conquered the home monitor now and its always normal.

Any help!?
