Sick and scared? Help?

I had a really rough day and binged quite a lot. I felt fine (apart from stuffed passed my comfort zone) and went to bed, knowing tomorrow would be better. But I just woke up because of a weird throat burning sensation. It's never happened to me and I've never made myself sick! It's like my throat is on fire but I'm not being sick. I'm a bit scared right now, What do I do? Anyone else experience this before?? How do I make it stop? Gargling water is not helping!
