I rarely have anxiety attacks myself--I'm really suffering from depression--but I know several people for whom anxiety and panic attacks are a major problem.
In treating my depression, I've used a drug-less, cognitive therapy that is described in the book, "Feeling Good: The New Mood Therapy"
by David Burns, MD. It really works!
Now, there is a drug-less, cognitive therapy for sufferers of anxiety and panic attacks; it too is written by David Burns.
I urge you to read: "WHEN PANIC ATTACKS: THE NEW DRUG-FREE ANXIETY THERAPY."
