Hm-m-m-m... well I don't really have what I think of as panic attacks. When I'm out in public, which isn't all that often, I just get progressively more anxiety-ridden until I finally get out of the situation. (There have been times when it got so bad I began to feel as though I was floating outside of my body.) Then, once I'm home, I get really tired. I don't really have any particularly good coping strategies. I just tough it out until it's over. If I'm in a shopping mall, I may try to find a quiet place to sit for a while. Or I might go to a quiet area of a bookstore if there's one available. Occasionally, I'll just go sit in the car or walk around outside for a while. The standard types of things that are typically recommended, such as deep breathing, actually make matters worse. One thing I've thought about, but never done, was to have some sort of "worry beads" to handle... don't know if having something like that to fiddle with would help or not...
