Extreme morning sickness at 12w-3d

I'm not having twins but today I was so extremely sick. I've thrown up everything and can't keep ANYTHING down. I know morning sickness can be elevated with twins but I'm only carrying one baby. I took half a unisom to get me tired but I think I threw that up. Anything I ate today was also thrown up as well as water. I don't know what to do because I honestly can't handle how it makes me feel physically and emotionally
