Hyperemesis Gravidarum

I went to the doctors this morning as every day the nausea and vomiting is getting worse and worse, he diagnosed Hyperemesis Gravidarum and said if it gets really bad I will need admitting to hospital. I’m led here feeling like absolute shit with a banging headache trying my hardest to keep everything down 😑. Half of me is like “it’s good, means everything is as it should be!” The other half is screaming for just 2 minutes of not feeling like death warmed up. Any tips, because this could last a while yet 😫. I’m 7 weeks on Friday.
