Severe stomach pain and dizziness

I am a 20 yr old normally pretty healthy female, I eat healthy and excersise regularly.  Lately, I've begun a somewhat gluten free diet because I realized that I'd get super tired to the point where my face is numb and I want to pass out immediately after eating anything with gluten.  Lately,  I have started to have extreme upper abdominal pain after eating anything gluten free or gluten products and I will get dizzy and naseaus.  I have yet to actually throw up but I get really sick to my stomach and dizzy and nothing makes it better, it just has to pass.  Additionally, I've been extremely exhausted, suffered from bad headaches, constant gas and bloating, eye strain, and just overrall feel really crappy.  I went to the doctor on monday and the doctor thinks I may have celiacs like I thought.  He drew blood to test for this as well as some weird stomach bacteria, but I have not got the tests results back.  I wanted to post on here to see if anyone had any suggestions.
