But if you have an anxiety disorder, this normally helpful emotion can do just the opposite – it can keep you from coping and disrupt your daily life. Anxiety disorders aren't just a case of "nerves". They are illnesses, often related to the biological makeup and life experiences of the individual, and they frequently run in families.
There are several types of anxiety disorder, each with its own distinct features. An anxiety disorder may make you feel anxious most of the time, without any apparent reason. Or the anxious feelings may be so uncomfortable that to avoid them you may stop everyday activities. Or you may have occasional bouts of anxiety so intense they terrify and immobilise you.
