Am I dying?

I'm 16f pots for 8 months as well as has suspected GERD. I woke up today, feeling super out of wack, not like how I normally feel. I usually feel okay-ish in the mornings and afternoons but today I feel like I'm dying. I woke up and my stomach started burning so badly, same with my throat. I tried to down a little bit of water but it didn't work. My head feels super funny and I'm sweating and trembling. And my chest feels so tight that I can't breathe, I have these symptoms normally with my pots and acid reflux but today they're on a whole other level. I dont know if I should go to the hospital or not, I'm just really freaking out.
