I'm probably not going to be much help with the medication as in England docters don't appear to perscribe any medication, but, and I know you will probably already know this, the increase in attacks is probably due to what you said, you are anticipating them, you are anxious about having a panic. I don't know what to say to help you, just keep trying to face them and hopefully you will remember that these will not hurt you. I am exactly the same, I constantly worry that something might happen to me, like I'll eat something and then worry it is poisoned or stupid things like that, but nothing has happened as yet!! I know I haven't helped much, I just wanted to say keep strong.
