brain fog

since my brain has been foggy, I've begun to do research on the issue. My allergies to food have gotten worse and I get massive when I bloat; this was not an issue a few years ago. My grandma was tested for celiac disease but I don't know what came of that. I should ask my dad. Anyways, brain fog can be a symptom of Celiac Disease or food allergies and I want to be tested. However, I pass out when I get blood drawn, so I really have to go out of my way to prepare!! I hate ittt,, I have to take someone with me probably. so upset bro
