My new cardiologist did the most sensitive, nice, amazing thing ever:
I had an outpatient apppointment regarding PoTS. I stood up in the appt for a few seconds and crumpled. 5 mins later I was still lying on the couch scarcely able to open my eyes and he says "if it is OK with you, what I would like to do, if you don't mind, is admit you for treatment here and now." I could have hugged him. Contrast to the other Dr I saw about 2 months before, who had seen me in exactly the same state and told me to do more exercise!!!!
Hallelujah for Drs who can see through a brave face and take HMS/EDS and its associated quirks seriously

And later, when I was in hospital he came to see me and found that pharmacy had messed up and I was way overdue my meds. my whole body went into shakey spasms every time I talked. It was awful. He sat down next to me and said "just relax. You don't need to explain. I've seen exactly the same symptoms in PoTS patients before - and no, it isn't psychological! (to the nurse) what is the ***** pharmacy number!" and proceeded to tell pharmacy that, well, shall we say, my meds were urgent. lol.
