allergy fear

over the past year or so i have really developed a fear of allergies, and specifically anaphaylactic shock. i think it all started just hearing anecdotal stories from coworkers, the news etc... and like everything else, i fixed in on it and it just slowly grew into this giant that i think about constantly.

i have been avoiding many things that i have never had a reaction to, mainly eating the same food or types of food everyday, over washing my hands and using extreme caution or discontinuing use altogether of household chemicals and stuff we use at work. that alone in itself is aggravating and making the situation and anxiety worse, i know i am just re-enforcing a false fear response in my body but as i've tried to explain to my therapist, it is easier to avoid and have 5 minutes of fear than face it and worry for days. i know thats not the long term answer but some days its all i can do to get through it.

at any rate, about a week ago my lip swelled up while working outside, i dont remember feeling a sting or bite from an insect but u guess its not out of the question. it did not swell huge, coworkers noticed but they weren't freaked out by the size or anything. i did go to the urgent care and he prescribed an anti inflamatory of prednisone and an epipen as well (scary) he did not administer any treatment and it was about 2 hours before i could have the rx filled and the swelling had gone down on its own by the time i took the first prednisone.

i know others have anxieties about allergies, and there are ways to cope, but i feel like this latest episode is re-enforcing my fear to the point where i am afraid to go outside, and when i see a bug buzzing around i am watching the clock for the next 30 minutes to make sure i am not having any signs of a reaction. i know i am driving my wife nuts and i need to get this fear under control, any tips?

s.c.
yes, he is aware and frustrated with me about it. he basically told me to go out and get living, to do things in spite of fear, and told me he didn't want to see me for 3 weeks. i was mad at him at first, but i see his point too of course, im not going to get better if i dont put the work in, but when i do see him again next week i will be able to give him a more broad picture of the issues again rather than my usual weekly ramblings, so i think the 3 week break is good because it has caused me to refocus on what the core problems are, and it will help me illiterate that to him better.
so yeah, i got off topic there i apologize. thanks for the response, i ordered a sandwich from a sub shop today about 2 hours ago and believe it or not i'm still alive! lol. can't remember the last time i let somone else prepare my food. tasted good, and feels good now.
