Good Morning MK,Noise anxiety - yes I have had this when I am feeling really anxious. For me it is usually when I am trying to rest and a sudden loud noise startles me - the phone ringing, the dog barking etc. I also do not enjoy loud, boisterous places where everybody is screaming and I cannot hear myself talk or even think !
You are not weird at all and I am sure that their are many of us right here in the forum that have the same response to noise tirggers. I have read of people who have had luck with overcoming noise anxiety by learning hypnosis. If you can find a someone who is skilled in clinical hypnosis it may be worth looking into.
Meanwhile remember you are not alone. I hope you keep on talking with us as we know where your coming from and what your going through.
Kindly,
Kitt
