Hi there,
Sorry to hear about your diagnosis! Here's a link to a list of books that are good. kidswithfoodallergies.org/books-adult.html
I personally own: "The Paren'ts Guide to Food Allergies" and Coss' "How to Manage Your Child's Life Threatening Food Allergies" I also HIGHLY recommend the website that I linked. At the height of things, I was dealing with milk, eggs, soy, wheat, peanuts and treenuts. And kidswithfoodallergies.org saved my life! The support was amazing and it was the best $25/year I've ever spent. (No affiliation, just a VERY satisfied user)
It's overwhelming and scary, but you can do it! We're vacationing in Disney this year specifically BECAUSE of how well they deal with food allergies. I hope it lives up to its reputation.
Good luck,
Joanne
