If you're forcing yourself to eat and drink at this point, you probably need an IV because I doubt with that soreness you're having that you can take in as much as you need (which is more than usual since you need to make up a lot of lost nourishment and fluids).
Cold with sweating is called "shaking chills". It's not uncommon with significant infections. But it does mean someone should figure out exactly what you have and treat it.
Lots of doctors think things are "just strep", often times because they don't want to do a lot of testing and/or think any more about it than they have to. Plus, "just strep" can cause a lot more serious infections than strep throat, and this sounds a lot worse than just strep throat.
My advice is to get yourself to an ER, urgent care, or the like, even just for a bag of IV fluid.
