Am I overreacting?

So I’m 8 weeks pregnant. I feel weak, dizzy, and I can’t keep any food down. I haven’t been able to leave bed much today and I am contemplating going to the hospital. I have a feeling I maybe dehydrated because I haven’t been drinking much. My boyfriend called in and says that I need to go. Do you think I’m overreacting? I just don’t feel like this is normal.
