Hi! I'm not completely over the fear, but I'm beginning to come to terms with the possiblility that this may be all anxiety and reflux issues! I'm not sure if this is the best thing, but I asked my dr. for an epi pen so I could eat again. I became about 10 lbs. underweight from never eating anything while alone. He agreed to give me one, and this has helped me tremendously. I would be to afraid to ever use the thing, but it's kind of a security blanket just having it around. My throat still feels tight and like it's swelling shut at various times, but it never has actually closed off. I've noticed that I do get burning acid in my throat overnight, and I've learned that this can cause the swelling sensation, trouble breathing, and itchy throat while the burn is healing. I'm still not sure the exact cause, but I do know that at least some of it had to be anxiety since a lot of it subsided once I got an epi-pen. Also, I only seem to get the really bad symptoms when I am alone, which makes me think anxiety as well. I read your other post about fear of allergic reactions, and just know that this is a very common fear among people with health anxiety. I have been able to find many more people with this fear that have never actually had a reaction, but yet the fear consumes their lives. Anxiety sucks so bad, I really feel for you! I'm sorry I can't be of more help since I'm still dealing with it. Hang in there!
