Yesterday at 11 am I started to feel sick to my stomach, my skin started to feel irritated, I started sweating profusely. Then the vomiting started for almost 12 hours straight. I would fall asleep really easily but would have incredibly stressful dreams, that would only last a couple minutes and then my body would force me to wake up. I went to sleep over and over but the longest I was able to sleep for one time was 20-30 mins. I also felt extremely confused and scared. 
This isn’t the first time it’s happened, in the last 6 months I’ve had three of these episodes, but the first two only differentiated because I felt like couldn’t breathe and I definitely was really scared, this last time my breathing wasn’t as bad, I was just a little short of breath. I went to the Emergency Room for the two first episodes, they gave me several different types of medication for nausea but it didn’t help. Both times in the end they gave me something to sleep. 

I tried to be as descriptive as I could, if I can think of anything else I will add it. But I would terribly like some help or someone opinion if this could be related to some kind of panic disorder?? I didn’t think it could be because the episodes were so extreme and lasted so long. I would appreciate any help or support! I’m honestly terrified of having another one of these episodes. Thank you!
