You didn't mention whether or not you have been prescribed medication for these episodes. I can honestly tell you that I've suffered with these for years, until I saw the right doc,(psychiatrist) and he prescribed a seizure drug that gave me my life back. I am very sorry to hear that it has been two years and nothing has been resolved for you. A tiny, but very significant point is, if you can control your breathing pattern, you can stop the attack from becoming "full-blown". If you go to my page, and look at the visitor messages, the message from TheByzantine explains a lot about how to prevent the panic attack from happening; it involves your breathing. Please try this. I pray that you find the right doc very quickly. Take Care. HUGS.............♥♥♥
