In my opinion you have hit the nail right on the head. We cannot give into the panic attacks. Don't pull the car over, don't leave the store, don't to the thing that you want to do which is get out of the situation you are in whatever it may be. If you are in the mall, sit on a bench but don't leave. If you are in your car, breathe, sing, hold your breath, you know it will go away at some point but don't pull over.
