Horrible "morning sickness"

I am about 10 weeks pregnant (still waiting on an OB appointment to get an ultrasound) and for the last 10 days I have had the worst sickness. My stomach hurts an incredible amount (actual stomach) when I eat or drink anything it gets extremely worse. It's to the point of me not being able to get out of bed, I am weak and dizzy..  I have called my doctor and the OB I will be going to, and they keep saying it's bad morning sickness... I went to the ER yesterday because I've lost 6 pounds in a week (no vomiting or diarrhea, just can't eat) and I wanted to know what in the world is going on. All they did was some blood work , said it was just high amounts of stomach acid & sent me home with an antacid.  I took the antacid, tried eating some toast and drinking water and now I am in bed with the same horrible pain as before!
