Hyperemises gravidarum

This is my 4th time with HG, you'd think I'd be dealing with it better... but I'm miserable. I've been to the hospital twice (I'm 11 weeks now) and just recently got back home from 3 days in the hospital. My body was dehydrated and starved. I have ulcers now from my stomach eating itself.... my HG has never been so severe. I'm starting to get so depressed. I feel like no one understands. :(
