Food allergies. i had food allergies for years when i was younger and was told i had grown out of them but...

last wednesday i was eating pizza and reeses pieces and my face and toung and throat became very swollen. back to the allergist i went now avoiding anything i'd ever been told i was allergic to, which is wheat, eggs, nuts, dairy, chocolate, and melons. i'm a chef and i'm miserable. i'm just waiting for the rast tests to come back. i keep thinking i'm going to lose my mind if i have to go back to eating like i did when i was younger. my career is over, i can see it beginning to happen already at work. i was just wondering if anyone had any idea if it could possibly be anthing else? i know it isn't but i could use some encouragement right now.
