I have no experience with your symptoms. Mine were limited to very high blood pressure and crazy heart rate. I was scared as hell too (which could not help neither the blood pressure nor the heart rate).
I am sure others will come with more insight than me, but I would try to make it to an emergency department. It will also guarantee you are not alone in case things go wrong. At worst you are sent back home after being in a safe space for a few hours. Keep posting.
