Sandel,
Firstly I am very happy that you have no cardiac abnormality. This is the one plus you have from this experience.
To be honest that doctor has just made a right **** of himself admitting that he has never heard of this disease, it is a big admission considering millions of people across the world have it.
To get some type of retribution (which I would definitely need) I would print up information for him about the disease and send him the names of all the doctors and psychiatrist whom you see so he realises it is he who needs psychiatric help and not you.

Please don't let it upset you anymore--you know that those who care about you know differently.
Love Tayla
