Hi Vickivdb,
Sometimes anxiety/panic can be caused by a physical problem:
The first thing your doctor should have ruled out are things like cardiovascular problems, asthma, seizure disorders, diabetes, hypothyroidism and problems with the inner ear.
Some drugs and medications can also cause anxiety problems for example: stimulants, thyroid supplements, cold medications, tranquilizers, sleeping pills, certain blood pressure medications, steroids, and even anti-depressants can cause anxiety symptoms.
Also, drugs such as caffeine, alcohol and marijuana can be another potential source of anxiety symptoms.
Finally, balanced nutrition, exercise (esp. cardio), and getting a good nights sleep are important factors that help your body to react to stress in a "normal" way.
With all of those factors ruled out it is generally either something that happened to us (ie: a traumatic experience), or a learned behaviour/ pattern of thinking that causes anxiety.
For me it is a combination of both. I've stopped doing drugs, I don't drink coffee or tea anymore, I eat better and go to the gym, I try to sleep at regular times and wake up at regular times. Now I have to work on my patterns of thinking that always seem to dwell on negative "what if's?", and other forms of distorted thinking that effect the way I feel on a daily basis.
I am now in therapy and am slowly learning how to identify and change these thoughts that I never really noticed before. The program on this site is designed to do the same thing. Keep at it, it'll only make you stronger.
