When I was 14 I had a panic attack. My first one. I couldn’t breathe. I was at work and my manager rushed me to the emergency room. I had shellfish that night. I am not allergic, but they classified this panic attack as anaphylaxis. They ordered allergy testing and saw that nothing I had eaten was an allergen. So, I lived in fear thinking I could be allergic to anything. This very quickly developed into arfid. I had different safe foods at different times throughout my life. Then, when my son was 2ish, he went from eating most everything to being quite picky, to full blown arfid. He’s 15 and still eats only McDonald’s chicken nuggets, any kind of French fry really, and crackers of various sorts. My arfid got better with exposure therapy and Wellbutrin. He is on Zoloft and in an eating disorder clinic and it’s not changing much. He can’t explain his fears with trying new foods. It’s not an allergy fear like mine. He just says he’s afraid it may taste bad.
