"I really hope it's gluten because if that's the case, I have a way to manage my UC. I'm scared to try gluten now because if I try it and I don't go into a flare, then I'll know it's just coincidence, and I don't want that to be the case."
and if you do go into a flare, in my experience, that can be scary too !
kinda why i will stick with a semi-strict (by my definition) diet - cuz if diet don't fix it, i'm back on the med train, only farther down the line - that's holy crappp scary !
