Hey... we all get frustrated at times with our parents when we are young... I know I did on more than a handful of occasions. Its alright, I can tell you love them a lot. I love my husband a lot too but I know that he doesn't understand half the stuff I go through so I usually feel like pulling my hair out at times.
You may want to just see about
avoiding gluten because sometimes those blood tests aren't very accurate. Actually for Celiac, the blood test is the least accurate, the biopsy a bit more accurate, but the real test is if the sx go away when you avoid the foods.
I hope you can find out whats going on sooner rather than later. Vomiting and nausea are horrible.
