Is the anxiety disorder self diagnosed or is it diagnosed by a professional? There are folks around who will self-diagnose an anxiety disorder or other psychological disorders because giving a name to troublesome feelings and behavior offers a sort of relief. Self diagnosis is even sometimes correct, but it's better if it's backed up by skillful professional diagnosis, which usually comes with a treatment plan.
Anxiety disorder, like many of the depressive disorders tends to respond well to cognitive therapy, sometimes called cognitive behavior therapy, which focuses on how the way people think gets them in trouble with their feelings. There are a fair number of people trained in cognitive therapy, and it is fairly widely available. I know that there are manuals for cognitive treatment of depression — there's a nice one by David Burns — and there may be some good self-help manuals for cognitive treatment of anxiety disorders. All this assumes that you have the right diagnosis.
There are often some factors in anxiety disorders that have an overlap with Adult Attention Deficit Disorder where the person has difficulty staying focused on single issues for long enough to put together any carry out plans of action. Their attention may hop about a bit.
I don't know how you feel about medication, but sometimes is can be helpful if it is is well prescribed. I'd suggest that you look at some of the books by Dr. Daniel Amen, who is pretty cutting edge as far as medication goes, and in some of his books provides questionaires and pretty thorough explanations for which medications may help which situations and — above all — why.
He even has a sort of cognitive therapy that he seems to have adapted for use with his drug approach.
You may also find group psychotherapy useful for this sort of thing. Group therapy is very useful for offering support and helping people to feel better about themselves. Depending on the therapist, you may also find it useful for making very specific changes in your life; but that depends on the therapist and the use you make of the group. Many groups are not oriented to that sort of specific work.
If I can be helpful in any way, please drop me an e-mail. I'll try to pass along back this way to see if there's anything I can do to follow up, so you won't need to e-mail, but if I don't get back to you in a day or two, feel free. I will be going out of town from time to time next month.
Take care, Juju,
