My throat!

So... I can't sleep at all.. My throat is like throbbing in a way.. I cant really swallow.. If i do..im about to vomit. My mouth is watery and my throat wants to hurl something up. Idk what happened. If i drink or eat something im about to let it all come up. If i try to take deep breaths.. Its making me burp and literally throw something up..

So im jus laying in bed and breathe slowly with a watery mouth trying not to swallow or freak out..

What's happening!!!
