dilemma. please help me.

So here's my dilemma. I've been sick, feeling like I'm dying for over two weeks now. Can't eat or drink but I force myself to eat small amounts all day. Crackers. Fruit. Smoothies. I've tried everything. By the end of the day, even though I've barely eaten anything, my food sits at the top of my esophagus and I am in pain until I make myself throw up. Everyone alround me is telling me it's just normal. But I don't feel like this is normal. Yesterday night was the first time I actually threw up blood and I've already been to ER once this week. I'd hate to go back for them to just tell me it's morning sickness and send me home again. What to do??????
