Internal difference between CC and eating gluten straight up?

Sorry if this is a stupid question. I was diagnosed like a month ago and my family just isn’t taking it serious at all. I explain to my dad how I’m uncomfortable with eating food that was cooked in a cracked ceramic pot due to possible cc, and he goes on about how I need to stop worrying about it. So I guess my question is- do my intestines react to the same degree if I eat a piece of bread, that they would if I ate a crumb? It’s just really hard, i feel like I’m second guessing the seriousness of my own damn disease. It’s just frustrating feeling like they don’t listen to me.
