Hi, I Am Currently In Kenya And It Will Be

Hi, I am currently in Kenya and it will be 4 hours before we can leave for the hospital. I have a fever, nausea, aches, constantly feeling cold, diarhea, and I vomited everything in my stomach a few hours ago while pooping. 2 hours ago my diarhea was 90% water. Just now I got out of my worst episode yet, I nearly blacked out from dehydration from so much water loss. It's now pouring out of me faster than my urine stream. Every 30-50 minutes I have had to run to the bathroom and sleep is nearly impossible. My last water pouring had a distinct smell of rotting fish, it was overwhelming. What steps should I take to allow me to survive until we leave for the hospital?
