Okay, the good news is that you say you know the source.  What triggered the anxiety.  Resolving emotional issues is not done overnight.  It takes time.  And it is very likely that the source of your anxiety can be traced back to your childhood.  The event that brought on the anxiety may have been just a trigger.  Don't give up on a psychologist or therapy.  Maybe you need to find the right person, someone you are comfortable with.

In order to relieve your anxiety try, first and foremost Bach Flower Remedies.  Go through the site and pick the Remedies that fit your particular needs.  

When healing from anxiety, one must address both the physical and emotional aspects.  Too often, they both go hand-in hand.

Below are some suggestions with regard to additional supplements that may help. 

Colloidal Gold:  This supplement works in a three-fold way.  It encompasses body, mind, and spirit.  http://www.utopiasilver.com is a very good source.  In fact, they have a first time buyer offer where you receive one bottle free for every 8 oz bottle ordered, but you must call them to receive this offer.  After that, by inserting coupon code LR001, you receive a 15% discount if it is not on sale.  Colloidal gold lifts one's spirits.

I have suffered from anxiety/stress related symptoms for 10 years now. I used the bio tuner with great success. I did take vitamin b6 (p5p) 50mg a day, about 600-800mg magnesium citrate/day, 400mcg folic acid/day, and Methyl B12 - 1000mcg every 2 to 3 days. I also used it in combination with a really good EMDR recording - stress management cd by Australian psychologist Mark Grant, which you can download here: http://voltahealth.com/proddetail.php?prod=CC-MP3 this in combination with the bio tuner made me feel like after a session of acupuncture (drowsy-but relaxed), as the recording is somewhat hypnotic. I generally used the #2 setting, seemed the most relaxing to me. I did two - 20 min sessions consecutively per day, sometimes I would add another session later on in the day.

My anxiety was so bad, I could not even walk into a store without feeling like I'm going to lose it. I would get dizzy everywhere in public, a vertigo feeling, my visuals and hearing would get amplified. I also had bad sweating episodes whenever I got really nervous for no apparent reason.

What pleased me the most about the bio tuner is it lessened my sweating problem due to anxiety by about 75-80%. and my general anxiety about 90%. I still have issues sometimes with panic in certain situations, but is much more controllable.

I plan to see a good hypnotherapist soon to resolve the problem once and for all, i suggest you find a good hypnotherapist in your area, as I truly believe hypnotherapy does work for matters of this kind. Anxiety and panic comes from your subconcious mind, and this is what EMDR and hypnotherapy target.

One other thing I would really recommend is taking at least 10g of good quality spirulina powder and at least 5g chlorella everyday, it will help your body and brain repair itself. Read the free ebook ChlorellaFactor.com

Good luck, wish you the best in your journey to good health! Your on the right track!
