Possible 3rd viral infection

I've had 2 viral infections within a two month period and I think I have another one. I'm nauseous, can barely eat anything, sweating but freezing to death, my throats killing me, my whole body hurts (especially my back), I have a headache, I've been exhausted all day, and I can't quench my third no matter how much water I drink. And about two hours ago I've became really weak. I can't even walk without holding onto something. I will be going to the doctor tomorrow if I still feel bad!
