Help me with my morning sickness!

Hi everyone! I'm 8 weeks and my doctor thinks I have HG. It's so bad. I don't vomit as much now. Maybe 2-3 times a day, but I have NO appetite to eat or drink anything whatsoever. I was admitted into hospital due to severe dehydration. Please, are there any mum's out there that experienced something similar? I'm so worried I'm harming the baby but I can't eat! I had a cheese sandwich today but it was soooo hard to eat! I'm sick of crackers. I can't drink lemonade. Everything tastes like poison. I'm like a dog with my senses. I can smell anything and everything makes me sick! Can't open my fridge door without getting sick. Any tips? I hope it passes soon.
