I suffered from extreme panic attacks that became almost constant for awhile, almost 30 years ago. This occurred shortly after a major loss (my Granny died). It was so bad for several months that I thought I must be seriously ill and/or dying. Gradually, with the help of a holistically-oriented M.D., I learned that a major shock or life change can precipitate anxiety and panic is susceptible folks, and coincidentally, I had crashed with major sensitivities to just about every chemical used in modern life. These crashes, when they happen, also commonly follow major change.
We tried a couple of different drugs to calm my system, and they only made things worse. But gradually I learned to do two things that brought me back to normal:
First: I cleaned up my personal environment – only unscented detergent and NO fabric softeners in the laundry, baking soda and vinegar for general cleaning, no scented ANYTHING, no food additives, replaced many synthetic materials in my home. It took months to work through all the changes, but I kept a diary and it became clear that I was getting better.
The other thing that became an absolutely central to my recovery was simply surrender. I had to learn to give up my belief that my individual life was so important that I could ruin it with worry. That might be hard to understand, especially as a young mother with a child depending on you. But all the worry in the world won't prevent accidents and illness, and in fact can actually help bring them on and make us less capable. So basically, I learned (mostly over one long and very difficult night) to turn it all over to God, or reality (they are closely related in my own understanding). And the panic faded, really very quickly after that, with no drugs.
I have found this sense of calm has served me very well many times since. What happens is what happens, and if that's something alarming or dangerous, I find I can often do what needs to be done while other people are running around with their hair on fire.
I don't know whether any of your imbalance has a physical cause, but if you're using most modern commercial cleaners, or foods that are processed and shelf-stable, you will almost certainly feel healthier if you find alternatives. And the second part of my recovery I can highly recommend to anyone carrying an supersized sense of responsibility.
I should mention, too, that I'm looking into EMDR therapy for a family member who has been traumatized recently. It looks promising. You might look this up and see whether it appeals to you – it's a non-invasive approach that's been extremely helpful for many people with PTSD and other anxiety disorders.
I wish you well, Sandy.
