Have you called your doctor? Maybe you should go to the hospital sounds like a lot is going on. I hope you feel better :)
I Experienced This Near The Beginning. What I Suggest Is If Your Having Troubles Eating, Try Have A Protein Shake Instead. It Gives You Enough Nutritence For Your Body To Function Somewhat. Always stay Hydrated, Try Ice Cubes In Your Water, The Cold Keeps You A Little More Awake. Hopefully This Helps You :)
