The biggest difference between those who suffer from generalized anxiety disorder and the population at large is the limited amount of control sufferers have over their thought processes. I used to worry uncontrollably about things over which I had little if any control. In fact, I often worried excessively about things that had no choice but to resolve themselves. My anxiety caused me to spend a great deal of time focusing on things that didn't merit the degree of concern I imparted them. Additionally, all the anxiety I felt over these everyday events wore on me, both mentally and physically.
Generalized anxiety disorder can be difficult to diagnose. I was lucky enough to have a physician who recognized some of the symptoms based on our conversations and recommended me to a specialist. Now that I've been diagnosed, I have successfully controlled my anxiety through behavior therapy, medication and relaxation techniques.
If you or someone you know feels overly anxious about the everyday events that all people experience, I encourage you to get more information on anxiety disorders. There are several excellent free resources on the web where you can view the symptoms of anxiety disorders to help determine if you may be suffering from anxiety. Always consult your physician regarding your medical concerns and remember, help is available.
