I do not know if this will help you, but it keeps me from missing out on life. I read a book, "A Road Less Traveled". which was recommended to me by my therapist. In the book the author advises. "Life is difficult, it is supposed to be difficult, accept it."
He says once you accept the pain it does not hurt so bad. That is not to say you shouldn't see if you can get professional counseling and get to a doctor for a physical to maker sure this nothing physically wrong that can be addressed to solve your problem. In fact accepting that you may have a problem that will require professional help may be stage one of recovery.
However, after all of that there was a second phase for me.
I am getting better at accepting the Panic Attacks, and as I get better, they have gotten fewer and less disabling. Maybe it is the medication, maybe as my therapist has suggested it is my understanding and acceptance of what is happening to me, but now while I still get the pounding heart, the dizzyness, the nausea, the physical urge to run away, a thourghly unpleasant experience. Now I know what is happening, I know it won't last, I know I'll come out of the other side, I accept that I can not prevent it. I accept the experience. I sit down, park at the side of the road, go back out to my car, whatever, it takes for moment of contemplation in a safe situation. I close my eyes and practice deep breathing and directed imagery for 5 or 10 minutes. I am no longer irrational.
It takes practice and I am still not perfect at accepting, but acceptance has for me eliminated the terror. That in itsself has reduced the stress that contributes to the attacks.
First, get professional help, because if there is something physcal that is causing it a simple pill may solve the problem for you. Maybe a professional therapist can give you a key that will eliminate the problem, or maybe all they can do is help you learn how to deal with it so you can accept this is just one of life's less pleasant experiences, accept it, and get on with the rest of your life.
I wish you the best in whatever you decide to do.
I do not subscribe to everything the author of a Road Less Traveled espouses, but accepting and dealing seem to be helping me.
