Hi keeponsingin and welcome to the board.
You say you have symptoms of gluten intolerance now. I guess your trial at gluten free wasn't very edifying for you without the cooperation of your family. You have to think about how you would feel later on if your symptoms improved some, but didn't improve all the way, and you didn't have a diagnosis. Would you still feel that you should eat gluten free? Or would you be tempted to say, well this isn't really working all the way so it probably isn't really gluten and OMG, that pizza looks and smells so good!!!
You see, that's the problem without a diagnosis for some people. Do you still have insurance under your parents' policy to get the full celiac blood panel run? That consists of:
Anti-Gliadin (AGA) IgA
Anti-Gliadin (AGA) IgG
Anti-Endomysial (EMA) IgA
Anti-Tissue Transglutaminase (tTG) IgA
Deamidated Gliadin Peptide (DGP) IgA and IgG
Total Serum IgA
If you get the blood test done you can know for sure (well, almost) whether or not it is celiac. If it isn't celiac it could still be gluten intolerance, but if you test positive on the blood work they will probably want to do an endo with biopsy to confirm the diagnosis. If they find a damaged gut they will know for sure it is celiac, an autoimmune condition that carries inherent risks with it if you continue to consume gluten. So it can be a very strong motivator when you start smelling the pizza
If you don't get the testing done now and just go gluten free and then start to doubt yourself, you would have to go back on gluten for at least a couple of months for the testing to be accurate, and some people find this an incredibly painful experience, so if you want the testing, now is the time. And you must keep eating gluten until all testing (including the endo) is completed.
Obviously, if you are living independently you don't have to worry about the school making meal plan accommodations for you. The only possible times being undiagnosed could be a problem would be serving in the military, getting gluten free food as a hospital inpatient, and (this one involves having the diagnosis) getting health / life insurance. Obamacare if it lasts may handle the first one and the other is an imponderable
So those are the major parameters you have to consider when you think about just going gluten free and seeing if it works. Many of us on here have done just that without major problems (I was hospitalized in a coma and they were able to come up with feeding tube food for me which was allergen free - although I did become quite malnourished on it
- but it kept me alive). Good luck on making your decisions and I wish you good health.
