Thank you for reaching out. Plenty of people have had this kind of experience. I have had this too. I have found some things that have helped me. Of course we are all having different experiences and different health problems so these may not work for you, but something to try. The first is for me to realize this will not kill me, and look at it as an experience to be analyzed. Keeping a record of what you have been thinking, doing and eating before this panic attack. Find any common occurrence and see if changing these helps. That brought up for that I was eating or drinking something with a stimulant. Chocolate, cola, tea, coffee, msg, artificial sweeteners are all stimulants that trigger anxiety for me. The third thing was dealing with stressful situations. Avoiding does not work for me. Realising that others have the same problems and that we all make it through has helped. Also doing something to work through problems keeps me going. The last item is medication. There are certain meds that help with anxiety. The best for me has been an antidepressant that also helps with anxiety. I hope that something from this list will help you.
