Frustrated

So while at my 20 week appointment today my doctor told us baby girl is doing great and right on track so for that I am grateful. Now on to me. I have been extremely sick and can’t keep down anything, vomiting after eating and most times drinking anything. I’ve lost 10 pounds. I’m not nauseous just throw up everything. My head has been pounding, less fetal movements (she’s fine) nurse could barley get a vein for blood after 30 minutes. She said I am severely dehydrated which I thought too since my urine is very dark. Well my doctor was no help and said well your baby is very healthy so I don’t know what you want me to do. Like wtf. Then was like well I guess you can walk across the road to the hospital if you want to but they won’t do anything except give you fluids.
