Hi angels... don't take this the wrong way, because I fully understand how devastating panic attacks are... but since yours usually get worse around this time I am thinking about 2 different things: one is that you are being (subconciously) triggered with something that happened to you during the same time of year? OR it could be allergies! Maybe you eat different foods begininng the winter etc? Maybe the winds or storms bring in different pollens (or certain trees or whatever are pollenating during this time?) I was so "brittle" as they called it with allergies, I had to go to my ENT/allergist on a private schedule in case I had a bad reaction to the testing... along with me was a lady whose allergies caused heart attacks! I know also of children who are "deaf" until their allergies are taken care of and then aren't! So allergies can do all sorts of weird stuff to us... just a thought or two.
