One thing that is good to remind yourself about is that panic attacks are not dangerous at all. I had those for about three-four months. The first times I was convinced the panic would never stop, that I would go crazy or die "mentally", but as it never happened my body and mind kind of learned that the panic attacks weren't dangerous and so I stopped worrying about them, and finally they went away completely. Talking about your thoughts or feelings or whatever it is that triggers the panic attacks, also helps a lot.
