Hyperemesis?

So for the last 4 days I have been unable to eat or drink ANYTHING without throwing up minutes later. I have a severe migraine that Tylenol won't even help, and overall I feel miserable. I've been to the ER twice and they gave me Macrobid (antibiotic) and Zofran (for the nausea). The thing is, this doesn't feel like normal pregnancy "morning sickness." And on top of that, I'm type one diabetic so this has been hell on my blood sugars which are very important for the health of my little one. I'm stressed out and I feel horrible all I can do is sleep and dream about drinking water. I'm so thirsty😩 The doctors and nurses at the hospital don't seem to know what's wrong other than labeling me as having "Hyperemesis," basically extreme vomiting. Anyone else experience this kind of problem during their pregnancy? I'm beginning to feel hopeless.
