Hello Pink.
Knowing what is causing the panic attacks certainly doesn't make it any easier, does it

Do you have a therapist? A therapist can help get you through this difficult time.
I have been using Sam-e for about a month with good results. Anxiety is listed as one of the few side effects so I was very leary about trying it. Well, it appears to have decreased my anxiety/panic attacks and in general I feel calmer. Like you, I knew the reason for the increase of anxiety/panic attacks.
