Among the most common symptoms of an anxiety disorder are: Daily or nearly daily worries about any (or every) aspect of life Inability to perform daily activities because you’re consumed with your worries or fears Feelings of danger Feelings of panic Rapid breathing Breaking into a sweat when your anxiety spikes Shaking Stomach cramps Upset stomach Weakness or tiredness Your specific symptoms due to an anxiety disorder can vary with the particular disorder and your individual life circumstances. With the most common type of anxiety disorder, however, symptoms are generally present daily or near-daily for at least six months. Anxiety disorders can sometimes look like other mental health disorders. For example, research shows that women with attention-deficit/hyperactivity disorder (ADHD) may be more likely to hide their symptoms. Because the anxiety symptoms of ADHD are the hardest ones to conceal, women with ADHD may be misdiagnosed with anxiety disorders in some cases. Adolescents generally have the same symptoms as adults, although parents may sometimes have difficulty identifying the symptoms if their teen doesn’t talk about their feelings. Some adolescents may start to withdraw from their friends, avoid new situations, or have frequent physical symptoms related to their anxiety.
