I wish I knew what the solution was.
I've talked to my mother about this, and found out that she had anxiety/panic attacks when she was about my age. I know anecdotes do not make for good data, but having read in several places that anxiety disorders appear to be hereditary in some form, my own personal anecdote makes good enough evidence for me to believe that there's some genetic predisposition to having this disorder. (My sister also suffered several panic attacks when she was around my age.)
But even given a genetic predisposition shouldn't mean that it cannot be "cured" (as opposed to just treated.) None of us have had this disorder our whole lives. It has emerged at some point. There should be a way to make it, um, disappear as well.
In my mother's case, she was in an extremely stressful situation when the panic attacks first made an appearance. She battled with anxiety for several years, was put on some sort of sedatives which she developed an addiction that took her a year to wean off, and beta blockers. She said the medication helped but only treated the symptoms; the anxiety didn't go away completely.
She finally found a way to remove herself from the stressful situation and her anxiety disappeared. She hasn't had a recurrence in 20+ years.
But that doesn't answer your, or my, question either. I obviously haven't found a way to beat this yet. Dealing with this is exceedingly frustrating to me. I do believe that simply because it hasn't always been there, I will find a way to "get rid of" it at some point in some way.
Somehow.. some way.. some day... :)
(And if I find a cure, I'll let you know :P)
