I have a damaged brain and central nerve center issues so I know all about panic attacks, you might want to ask your doc to take a look at the central nerve center and/or the connection between the two brain halves.
If they're "just" panic attacks then it might indeed be that you're vulnareble to stress, in any case I hope you'll be fine
I agree with whats said before, Polaris nice healthy Vektor MUCH more important
