Hi marianne,
I understand how you must feel. I am someone who has had more than his fair share of anxiety and panic attacks in life. I've had my share of depression as well. But no more.
Yes Spring Forest Qigong WILL help you. IF you do it regularly.
SFQ has helped me in this way tremendously. So of course I recommend it. Be sure to include regular meditation as well.
Qigong is all about balance. When we have anxiety our bodies are out of balance. Namely the liver. Watch this video on youtube about one of the six healing sounds to balance the liver.
http://www.youtube.com/watch?v=GqDQCufkOHkI also would HIGHLY HIGHLY recommend regular exercise. If you don't do this already please find something that you enjoy that gets you up and moving. There are numerous test and studies that show the healing power of vigorous exercise.
Lastly when doing Qigong remember to keep a slight smile on your face.
