I Think A Layer Of Tounge Skin Came Off While

I think a layer of Tounge skin came off while I was sleeping . I woke up in the morning and drug my teeth across my Tounge and there was a lot of what I think was skin. I also have a terribly sore throat and anything that touches my Tongue gives me pain. It hurts to drink water. The day before I was drinking which I do all the time and eating sea food which I never do. What could cause this?
