That sucks he should have been there with you. I have ridden in an ambulance twice, once with a pregnant woman about to give birth and I was the only inexperienced doctor they could spare, second as a patient near death from a pulmonary embolism. That you COVID vaccine....

I'm glad you are recuperating. EMT's are usually idiots in my eyes, although I have met some smart ones. Assuming you had anxiety and no understanding of POTS is terrifying. They could have killed you... I'm sorry you had to go through that. That really sucks!
