Believe it or not - there are many of us here who can understand. We have pulled back and held with baited breathe when ourselves or our kids took bites. And were horrified when our allergy lists grew, not shrunk. Last November, I thought my 4yo escaped the curse of food allergies - she was 4.5 and had no issues, she had anaphlaxsis to macadamia nuts. And a few weeks later, to Nutella.
And many of us unfortunately have dealt with professionals that are tools. My ped told me kids don't develop allergies until the age of 2 - when DS1 was failure to thrive, covered in a rash, while I was breastfeeding. When I pushed for a second opinion, he reluctantly gave me the name of a clinic who just ran basic tests, told me to get rid of the dog and sent me on my way. DS1 had anaphylaxsis to barley and when I called them they told me barley couldn't have caused it, it was clearly nut contamination. I drove to the ER regardless.
Another allergist decided my son was too skinny and he was clearly eating foods he was allergic to so she went through with testing - wheat, rye, barley, corn, rice, oats, eggs, dairy, soy, peanuts and tree nuts. Why? Because she was an enviromental allergist who thought she could handle food allergies.
It's why I was urging you to find someone who would not blow you off and direct you in a better direction
