Sorry not to get back to you to soon Judy-m
But chemicals started me to have P/A's as I was a Autobody painter and got way overexposed to them and keep ending up in the ER from any chemicals (perfumes, cleaning products and so on) as they would put me into an attack. You would really be surprised how many chemical that do cause anxiety in ppl
You should look up on the net on some of the house hold cleaners and even make-up for women, it's all around us (look under MSDS on chemicals) that wife uses, you will find that a lot of these chemicals do cause anxiety with in ppl but at the same time they can help but for natural cures I really don't know of any and my wife works at a heath food store.
But for me I found Lexapro helped but but I had to really put my mind to doing something for myself to help get over it by pure fighting it and not letting it win me over any more so I pushed myself to the limits even with this fire coming I'm still calm and still in control.
Sometimes ppl look for years on end for what triggers them to happen and it can be right in front of you but the hard part is within the mind to fight back the fear that has developed and learn from it.
