Anxiety is the reaction to stressful situations and can be diagnosed as a mental disorder. It can come in many different forms, such as panic attacks or phobias. Comparatively, anxiety is different from fear in that fear is a reaction toward an immediate threat, and anxiety is a feeling of dread or nervousness over anticipated events. Additionally, this condition doesn’t have to have a direct cause since it is sometimes fear of the unknown. Therefore, treatment can be trial and error to find helpful coping mechanisms.
