Everyone has periods of feeling anxious in their lives. Anxiety disorders affect 40 million Americans a year, according to the National Institute of Mental Health. Some anxiety is normal, but if worries and fears are preventing you from living your life freely, you may be dealing with an anxiety disorder. People with generalized anxiety disorder tend to be afflicted with excessive worrying over everything and anything. They have trouble with racing thoughts, worrying about little things, and blowing things out of proportion. They can’t stop worrying or slowing their thoughts down. If left untreated, anxiety can lead to serious physical illness as well as mental illness.
