Treatments that are known to work include the anti-depressants, such as Celexa, Lexapro, Paxil, and Zoloft (to name a few), therapies, such as cognitive behavioral therapy, exercise, and omega 3/fish-oil. There are also many other activities that one can do, to support the healing of the mind. These include keeping oneself hydrated, drinking plenty of water, a healthy diet rich in whole grains, fruits and vegetables, meditation, and mindfulness.
Anxiety Zone is a goldmine of valuable information, located on all of the sites, and including the GAD and Medications/Therapy sites. I have learned so much from the forum, and have made some wonderful friends.
The very best to you, Worldbeat!... Chuck
