Struggling with Gluten Sensitivity and Contamination in Shared Kitchen

Getting pretty tired of this gluten sensitivity. I had been recovering from COVID, so I had zero appetite, just getting it back. I don’t enjoy sweet any more. Tolerate salt. I have EOE, which makes it hard to swallow and also have heartburn with it if I eat gluten, even small amounts. Allergy test came back negative surprisingly but allergist recommends I get an official test for Celiac. I’ve recently been experiencing lung pain and inflammation plus diarrhea and intense stomach pain even with small amounts of contamination. I’m miserable because I don’t have my own kitchen (living with in laws now due to helping dying mom-in-law, as I’m the only nurse in the family). So the kitchen is riddled with contamination. Being a night shifter, I struggle with food and sleep already. Been eating about one meal a day and have unintentionally lost 20 pounds. At least I can afford to as I’m overweight. This is getting exhausting. I just want easy food lol. Help? Recommendations?
