seeking support while raising a son with peanut allergy

As an expectant second-time mom, i read every piece of parenting literature available. When my 5 month old son, who is now 11, first experienced hives after eating his first bit of solid food, a left-over PB&J sandwich, i drew on the knowledge I had previously read about food allergies. I called immediately and made an appointment with an allergist. He was too young to test right away so at 7 months we had the whole array of skin tests performed.
He tested positive on the skin pricks for an abundance of tree, pollen, egg, milk, fruits, etc. but no peanuts. To be certain, they injected a bit of peanut under the skin and immediately the reaction was huge. Since then we've been super vigilant to stay away from all peanut and peanut products, peanut flour, etc.
We now know the skin anomaly he had when he was 4 months old was most likely a reaction from the peanut oil in the air while we deep fried a turkey. His little legs swelled up and chaffed terribly. He was in so much pain.
Over the years he's managed to stay reaction-free.
He was just re-tested last week and still shows a class 6 for peanuts.
He's never been happy to have this allergy as it usually singles him out as different while at school, sports, etc. He has to always ask "does this have peanuts in it" and treated differently because of it.
