Morning sickness overload

For 2 weeks now I have been sick morning, noon, and night. I'm miserable. I can't stand for long periods of time without getting awful waves of nausea. Everything I eat comes right back up. I drink so much water but feel dehydrated. My back hurts so bad that it makes me puke. I've tried ginger, lemon, jello, crackers, pop sicles, bananas, soup I'm running out of ideas. I'm so uncomfortable and sick that I can't stop crying. I feel Like such a baby.
