It has also been awhile since I have had a full blown panic attack, but I have had periods of high anxiety where I was scared of an attack. And then times where I just plain worry about them coming on…That is part of my anxiety disorder. For me just forgetting about them does not work. I once read something along the lines of trying to intentionally forget about pink elephants will make you think of pink elephants all the time. I am not sure if that makes sense to you, but what it means to me is the more I try to forget about my panic/anxiety, the more it pops into my mind.

What I have done to deal with it is talk about it in therapy. Come up with ways to resolve the anxiety—its sounds like you are already on the path of that by yourself. Maybe a little professional help could help you overcome the worry or dread of future attacks. I know it has helped me.
