Anxiety & panic attacks
Everyone experiences anxious moments at times. Anxiety is a normal response to danger. But if you are excessively fearful or in panic for no apparent reason, you might be suffering from an anxiety disorder. You avoid everyday situations out of fear of having a panic attack, but it does not help. By avoiding situations, your anxiety only gets worse.
Panic attacks are accompanied by heart palpitations, shortness of breath, sweating, feeling dizzy or faint, and nausea. A panic attack can lead to persistent anxiety fearing further attacks.
Other forms of anxiety disorders are obsessive-compulsive disorders and post-traumatic stress disorder.
