the throat closing up sounds like an allergic reaction....i wouldn't say anxiety. You would know if thats what it was, ya know? That sucks it turns out ur allergic..i can't say i've ever heard of anyone being allergic, however I have met people that can't smoke b/c of anxiety...(they think there throats closing up but its not) like more mental than anything.....does this sound like u?
