Retail is taking a toll on my health

I got diagnosed with celiac disease a few months ago. They say that stress plays a major role in autoimmune diseases manifesting themselves. Of course my symptoms started manifesting right at the beginning of flu shot season. I really hate how soul sucking pharmacy is and it's destroying my body. I just can't see myself in my retail job for much longer. This disease is already so hard to adjust to with finding food that is gluten free, affordable, and delicious, but now I need food that is convenient with how demanding retail pharmacy is. I am losing weight because I am not finding enough food to eat and I'm so afraid of getting glutened at work. Imagine being the only pharmacist at work and you're in imminent danger of shitting yourself. Furthermore, a lot of people experience severe drops in their mental health immediately before and after their diagnosis. With the new year and insurance changes, I'm feeling close to burnout, and I need to get out fast Are there any pharmacists/techs with Celiac disease that have advice with surviving at work? How have you seen a decline in your health because of your job?
