THIS PERIOD IS ACTUALLY KILLING ME

I have been nauseous, on the verge of vomiting, for a week now. I've barely been able to eat anything and I'm losing so much weight. I weighed 93 lbs to begin with and now I'm down to 90 and I absolutely cannot afford to lose anymore or I'm going to have to go to the hospital. I've taken the multi symptom Imodium, drank kombucha and loads of green tea and lemon and ginger tea, and taken straight up ginger capsules. I'm so light headed and nauseous I can't even get up to try to get food or water for myself right now. I've been on the pill for nearly 2 years, I'm not sexually active, this has never happened on my period before and I don't know what to do. I'm positive it's not a stomach bug as well, this just feels like a period from hell. Btw I don't have any zofran, but would Zantac help at all? 
Edit: I don't want to get into it, but for several reasons I do not trust doctors for anything more than a checkup and will absolutely not be seeing one.
